Cookbook Using Variants in REA ProcessesIntroduction to the REA master data modelThe REA master data consists of two main objects: REA article and REA (packaging) component.A REA (packaging) component is based on REA internal fractions. Figure 1 depicts the master data modelschematically. The colors in Figure 1 will be used consistently throughout this document.ArticleComponentFractionFigure 1: REA Master data schemeREA article and REA components refer to the material number in the ERP Material master (MARA-MATNR).Hence REA article cannot exist without a corresponding MM entry. REA packaging components may existwithout a material master entry, if configured appropriately. In addition it also is possible that a REA articleand a REA component refer to the identical MM entry (Figure 2).ArticleArtikelAccess isRead- onlyComponentMaterial masterimR/3Figure 2: Relationship to ERP Material masterSAP COMMUNITY NETWORK 2012 SAP AGSDN - sdn.sap.com BPX - bpx.sap.com BA - boc.sap.com UAC - uac.sap.com4
Cookbook Using Variants in REA ProcessesREA internal fractions are maintained in the REA customizing and assigned to one or many recycling partnerfractions (Figure 3). It is also possible to assign an internal fraction to a recycling partner fraction withoutspecifying a partner fraction. In this case there is no settlement with this particular recycling partner for thatinternal fraction. This mechanism is called cancellation of partner fraction requirement. This fractionassignment is out of scope for this document.Internal fractionSynthetic fibreRecycling partner AFraction:Fraction: PlasticRecycling partner BFraction:Fraction: PlasticsmallRecycling partner CFraction:Fraction: Plastic partsFigure 3: Assignment internal fraction to recycling partner fraction by CustomizingAn internal fraction in REA is a packaging material that can be assigned 1 to n times to a REA packagingwith a defined weight / weight unit.A REA component consists of one or many internal fractions and that can be settled with one or manyrecycling partners. Both assignments are time dependent, so that several packaging versions with a nonoverlapping timeframes can be created. A REA component can be of type consumed packaging, which canbe directly identified in material movements by the declaration system, or of type sales packaging, whichcan be assigned to one or many REA articles as a component.A REA article represents finished product that must be reported to a recycling partner due to the legalobligations of the REA user. In addition to the material number, a REA article is identified by the key valuescompany code, country and sales unit. REA components and recycling partners are assigned to REA articlesin a time dependent manner. A REA article is directly identified in billing documents and/or materialmovements by the declaration system.Figure 4 depicts the REA master data structuring. The REA article and the REA components are the twomain components that form the REA master data. In addition to the keys and relationships explained so far,REA articles and REA components can hold various attribute values that are generally dependent on theassigned recycling partner.REA ArticleBottle(n:m)CapREA ComponentBottle(1-n)REA FractionAluminiumPlasticLabelGlassLabelFigure 4: REA Master dataSAP COMMUNITY NETWORK 2012 SAP AGSDN - sdn.sap.com BPX - bpx.sap.com BA - boc.sap.com UAC - uac.sap.com5
Cookbook Using Variants in REA ProcessesREA components are maintained by the transactions J7L5/J7L6/J7L7. The tab fraction is used to maintainthe internal fraction assignment. The tab partner is used to maintain the recycling partner assignment. AREA component can only be settled with partners that are assigned to the packaging in a particulartimeframe.REA articles are maintained by transactions J7L1/J7L2/J7L3. The tab packaging is used to maintain theREA component assignment. The tab partner is used to maintain the recycling partner assignment. A REAarticle can only be settled with partners that are assigned to the article in a particular timeframe. In casethere are multiple recycling partners assigned in the same timeframe, license fee splitting rules enable theuser to split the license fee of the packaging between the assigned recycling partners dependent on thebusiness process.REA articles can alternatively be maintained as reference articles by transaction J7L0. Reference articlesare settled exactly as their referenced article. Reference articles are not discussed in detail in this document.Figure 5 summarizes the REA master data maintenance process.(Packaging) ComponentArticleFractionassignmentRecycling partnerassignmentReference ArticlePackagingassignmentRecycling partnerassignmentSplitting definitionArArticleticleReferencing typedefinitionArticle assignmentArArticleticleCom p on en tArArticleticleComComppononenenttFr act io nCom p on en tFr act io nFr act io nFigure 5: Process viewSimplified data model with article, main packaging and additional componentsMany REA customers do not need all functionalities of the REA data model outlined above.

Cookbook Using Variants in REA ProcessesREA article and packaging variantsWith REA EHP6 the new key field variant was added to the REA article and packaging. That means in detailthis field is a new differentiation criteria for articles and packaging in REA. The variants are considered in theassignment between article and packaging as well as in reference article.As already known, it is possible to assign a packaging independently from a variant once to an article.Hint: The variant field with value initial will be considered as a valid variant also.Business Function J 7L REA AUTO CONFIGREA variants will be delivered with Enhancement Package 6. In order to make it available the businessfunction J 7L REA AUTO CONFIG has to be switched on via transaction SFW5.CustomizingAfter switching on the Business Function it is possible to activate the REA variants in the General Control(transaction J7LC) of the REA customizing. The screenshot below shows the related indicator, whichcontrols the usage of the Variants according to the REA master data. If the variants can be used, all REAarticle and packaging exists with an initial REA variant. Due to the reason of compatibility only the initialvariant is valid for productive REA declaration runs. This logic can be changed with a new BAdIimplementation as described in this document. As prerequisite the indicator for the “Use Controls for MasterData Maintenance” must be activated.Figure 4: REA Customizing: General ControlSAP COMMUNITY NETWORK 2012 SAP AGSDN - sdn.sap.com BPX - bpx.sap.com BA - boc.sap.com UAC - uac.sap.com8
Cookbook Using Variants in REA ProcessesArticle DialogThe representing fields of the variants can be found in all REA master data dialogs. The example shows theREA article dialog with REA article 501 and variant 0001. The assigned packaging 10 is the only packagingwith an initial value as variant.Figure 5: REA Article DialogAdoption of an example scenarioWith an individual implementation of a BAdI it is possible to adopt the REA variants to a business process. Apossible scenario could be a batch process dependent assignment of packaging variants to an articlevariant.In this example the type of a packaging depends on the vendor of an article. If the article is brought to marketthe information of the vendor is necessary to determine the correct packaging of this article within REA.In general the vendor is not considered in a SD billing document, which may be used as data source for aREA declaration. If batch management is used, it is possible to determine the vendor in the relatedpurchasing documents, which are linked over the batch number.With the help of a BAdI implementation it would be possible to get the necessary information to assign thevalid article variant according to a billing document.This scenario is also valid for the determination of the country of origin for a material instead the vendor. Inthis document both fields are considered when it is helpful.SAP COMMUNITY NETWORK 2012 SAP AGSDN - sdn.sap.com BPX - bpx.sap.com BA - boc.sap.com UAC - uac.sap.com9

The table is used if the batch management is plant dependent. Otherwise the table MCH1 containsthe cross-plant batch processing information.If the vendor (field LIFNR) is a criteria for the article variant, maybe it is a good idea to create an own table incustomer-namespace e.g. ZREA VARIANT to maintain a material, vendor dependent assignment to aREA variant. It is also possible to define the REA variant equal to the vendor, so the assignment would beimplicit. Another criterion for the variant determination could be “Country of Origin of Material” (field HERKL).A flexible beginning of such a table could contain the following fields. For maintenance purposes amaintenance view should be generated for this table (transaction SM31).SAP COMMUNITY NETWORK 2012 SAP AGSDN - sdn.sap.com BPX - bpx.sap.com BA - boc.sap.com UAC - uac.sap.com10

Cookbook Using Variants in REA ProcessesBAdI ImplementationVariant to business process assignmentThe assignment of the business processes to variants can be control in context of the UI, declarations andSD or Purchasing conditions. Each context is represented by a method of the implementing class.The UI context is a building block which controls the behavior of the variant field in the dialogs. For examplethe F4-Help, the F1 documentation, a default value, a check routine and the visibility of the variant field canbe controlled or defined with this context.The declaration context is another building block which adopts the REA variant according to the datacollection within REA. It is possible to determine the respective variant based on the transactional data whichare processed. Further on the REA article dependent declaration key can be controlled and the transactionaldata can be influenced after processing the REA data filter for business scenario purposes.The conditions context enables the control of condition type and a variant dependent characteristic andfield value, so it is possible to consider different REA variants in the SD- or MM-pricing.Hint: It may be useful to collect all technical objects in a special development package.Class implementation for each contextAt least one implementation with reference to the interface has to be implemented for each context.Each class can be instantiated with the respective method of the BAdI Implementation, which is described inbelow.It is useful to define the aliases for the methods without the interface name prefix.These 3 necessary classes have to be implemented in the following way: Create a class for the UI context and assign the interface /J7L/IF UI MAPPER.Constructor: Add a constructor with the parameter manuallyIN TCODEType SY-TCODEIN RUNTIME INFOType FPM S RUNTIME INFO.The initial assignments of the parameters is:method CONSTRUCTOR.me- transaction code in tcode.me- runtime info in runtime info.endmethod.SAP COMMUNITY NETWORK 2012 SAP AGSDN - sdn.sap.com BPX - bpx.sap.com BA - boc.sap.com UAC - uac.sap.com12

This instance refers to an individualclass, which inherit from the respective interface. The assignment of the class has to be done in the codingof methods as a type definition of the object. So it is also possible to assign different classes according toinput parameter of the interface.An example for each method is shown further down.

Theindividual methods control the determination of the variant in the declaration system and its updating whencollecting transaction data. The following methods are available for this: GET VARIANT VFV1This method is called during processing billing documents (table VBRK and VBRP) and returns a variant.For the example scenario a select statement with VBRP-MATNR and VBRP-CHARG from the tableMCHA returns the vendor number. In a second step the REA article variant could be determined in themapping table Z REA VARIANT for the combination. If necessary the BUKRS and LAND1 can befound in the VBRK. If the field WERKS is a criterion also, it is considered in the VBRP. GET VARIANT VFV2This method is called during processing billing documents from REA specific infostructures. This methodcannot easily used in this scenario, if the batch number is not be available in the source table. Usually theindividual source document is no longer available due to aggregation reason. GET VARIANT MSEGThis method processes material movement documents (table MSEG). In general the vendor information isavailable in this table, so it would be necessary to determine the variant in the mapping table ZREA VARIANT only. GET VARIANT GENERICThis method can be called from an individual data collector. This data collector is maybe part of customerdevelopment project.

Cookbook Using Variants in REA Processes MODIFY KVFM and MODIFY KMVDYou use this method to influence the updating of transaction data in each data collector when collectingdata. The method is called for each transaction data record that runs successfully through all REA datafilters. The return parameter can be used to suppress the updating in the data collector.According to the batch processing scenario this method can be used to evaluate the FILTER of the table ZREA VARIANT .For protocol purposes it is recommended to add the relevant filter information into protocol of the relateddata collector. This example shows how this can be implemented:The object i kvfm represents an item line in this example. It is recommended to choose the message type„I‟ (Information), because a message type „E‟ (Error) results in a termination of a declaration run.i protocol can be defined as type BALMI.Protocoli protocol-msgty 'I'.i protocol-msgid 'xx'.i protocol-msgno 'xxx'.i protocol-msgv1 i kvfm-matnr.i protocol-msgv2 i kvfm-variante.CALL FUNCTION 'J 7L MAINTAIN LOGFILE'EXPORTINGi msgid i protocol-msgidi msgno i protocol-msgnoCHANGINGc msgty i protocol-msgtyEXCEPTIONSOTHERS 1.IF sy-subrc EQ 0.APPEND i protocol TO io protocol.ENDIF.2.Class for UI context (Interface /J7L/IF UI MAPPER)Mapping of Variants in User InteractionThis interface allows you to map REA variants to ERP processes flexibly during user interaction. The individualmethods control the behaviour of the interface element "variant" in all REA master data dialogs and on theselection screens in reporting. The following methods are available for this: GET F4 CONTENTThis method allows you to implement your own input help (F4) that displays the variants available to theuser in the respective context.This screenshot shows the F4-Help implemented within the example „Design‟ scenario implementation.The F4-Help returns the available variants „initial‟ and „ANNIVERSARY‟ for the chosen article „MAT 2‟.This method allows the adoption of the F4-Help for different screens separately.SAP COMMUNITY NETWORK 2012 SAP AGSDN - sdn.sap.com BPX - bpx.sap.com BA - boc.sap.com UAC - uac.sap.com18
Cookbook Using Variants in REA Processes Figure 10: F4-Help in Article dialogHint: The class /J7L/CL UI DESIGN MAPPER include an example for this method. CHECK VALUEThis method allows you to implement your own entry check that checks the entry in the variant field for theuser in the respective context. If the check fails, the next dialog step cannot be executed.The check value method could also be used to check the authorization rights of a user. The authorityobject and the affected fields are:OBJECT 'J 7L VARIA',FIELDS ID 'BUKRS', ID 'LAND1', ID 'VARIANTE',The possible actitities are:ActivityDesciption01Create or generate02Change,03Display,16ExecuteThe method could be copied from class /J7L/CL UI DESIGN MAPPER and be adopted if necessary. Inthe class /J7L/CL UI DESIGN MAPPER a private method CHECK AUTHORITY centralize this check. GET FIELD HELPThis method allows you to implement your own field help (F1) that provides a documentation object for theuser in the respective context.The meaning of the variant in the business process can be described here. GET DEFAULT VALUEThis method allows you to assign a default value to the variant field in the dialog for the user in therespective context if the default assignment via the parameter ID J6Q is not meaningful. GET SCREEN OBJECTThis method allows you to change the properties of the variant field (visibility, behaviour) in the dialog forthe user in the respective context.SAP COMMUNITY NETWORK 2012 SAP AGSDN - sdn.sap.com BPX - bpx.sap.com BA - boc.sap.com UAC - uac.sap.com19
Cookbook Using Variants in REA Processes GET TEXTSThis method allows you to change the description of the variant field in the dialog for the user in therespective context.The text of the variant field could be changed to meaningful description according to the examplescenario. (e.g. ‘vendor variant’) GET DECLARATION KEYThis method allows you to influence the generation of the declaration keys in the dialog for the user in therespective context.3.Class for Conditions context (Interface /J7L/IF CONDITION MAPPER)Mapping of Variants in Condition AdjustmentThis interface can be used to control the reading and writing of condition records, depending on the business useof different variants. The methods allow variant-specific assignment of characteristics with assigning of respectivevalues and the change of condition records during update. In addition, varying condition types can be determinedfor the respective variants.According to REA specific SD- or MM-conditions this class can be used to control the creation or update ofcondition records and it is possible to define one additional characteristic. This characteristic has to be consideredin the related REA condition tables and the belonging access sequence also.The condition type can be determined according to partner, company code, country the currently assignedcondition type and the R
