[former_member262538]

In these blog I am going to help you ,

How to create the BOPF Objects automatically using CDS views.

How to Publish Odata Service in the Back End.

Overview of BOPF: https://archive.sap.com/documents/docs/DOC-45425

Overview of CDS: https://blogs.sap.com/2016/09/26/core-data-services-cds-in-sap-s4-hana/

Kindly go through above links to know more about CDS & BOPF

i.e These is the new ABAP Development.

Creating the business object using the cds views to enable ODATA service enabled:

1.Root node creation for example : ZBO_MARA (Root node)

For the root node need to specify the annotation: @ObjectModel.modelCategory: #BUSINESS_OBJECT

Zbo_mara is the Root node and created the associations with zbo_marc and zekpo nodes

@ObjectModel.compositionRoot: true



@ObjectModel.modelCategory: #BUSINESS_OBJECT



@AbapCatalog.sqlViewName: 'zbo_mara1'



@AbapCatalog.compiler.compareFilter: true



@AccessControl.authorizationCheck: #CHECK



@EndUserText.label: 'marac'



@ObjectModel.writeActivePersistence: 'mara'



@ObjectModel.transactionalProcessingEnabled: true



@ObjectModel.createEnabled: true







@ObjectModel.updateEnabled: true



@ObjectModel.deleteEnabled: true



@OData.publish: true







define view Zbo_mara as select from mara as ma



association [0..*] to Zbo_marc as mc on $projection.matnr = mc.matnr



association [0..*] to Zekpo    as ek on $projection.matnr = ek.matnr



{



ma.mandt,



ma.matnr,



ma.pstat,;



/* Associations */



@ObjectModel.association.type:  [#TO_COMPOSITION_CHILD  ]



mc,



ek



}

 

After activation, the CDS, there is a new BOPF. You have to generate the classes and activate it.

Then use CRUD Template in Web IDE.

Business object created in the back end,Please find the attached screen shot:



Double click on the BO , Popup get opens with information message (Business object is generated from the CDS VIEW)



ZBO_MARA  bo got created in the back end:



 

 

2.Child node Node creation zbo_marc association with the root node and zekpo

 

@AbapCatalog.sqlViewName: 'Zbo_marc1'



@AbapCatalog.compiler.compareFilter: true



@AccessControl.authorizationCheck: #NOT_REQUIRED



@EndUserText.label: 'material detail data'







@Search.searchable: true



@ObjectModel.semanticKey:  [ 'Matnr', 'Werks' ]



@ObjectModel.representativeKey: 'Werks'



@ObjectModel.writeActivePersistence: 'marc'



@ObjectModel.createEnabled: true



@ObjectModel.deleteEnabled: true



@ObjectModel.updateEnabled: true



@ObjectModel.transactionalProcessingEnabled: true



define view Zbo_marc as select from marc



association [0..*] to Zbo_mara as _Ma on $projection.matnr = _Ma.matnr



association [0..*] to Zekpo    as ek  on $projection.werks = ek.werks



{



@Search.defaultSearchElement: true



key matnr,



key marc.werks,



@ObjectModel.association.type:  [#TO_COMPOSITION_PARENT,#TO_COMPOSITION_ROOT]



_Ma,



@ObjectModel.association.type:  [#TO_COMPOSITION_CHILD]



ek



}

Child node ZBO_MARC created in the back end with the associated associations to the root node(ZBO_MARA) & parent node(ZBO_MARA)



 

3. Node creation zekpo association with the root node(zbo_mara) and parent node (zbo_marc)

 

@AbapCatalog.sqlViewName: 'zekpo_1'



@AbapCatalog.compiler.compareFilter: true



@AccessControl.authorizationCheck: #CHECK



@EndUserText.label: 'purchase order'







@Search.searchable: true



@ObjectModel.semanticKey:  [ 'matnr' ]



@ObjectModel.representativeKey: 'matnr'



@ObjectModel.writeActivePersistence: 'ekpo'



@ObjectModel.createEnabled: true



@ObjectModel.deleteEnabled: true



@ObjectModel.updateEnabled: true



@ObjectModel.transactionalProcessingEnabled: true



define view Zekpo as select from ekpo



association [0..*] to Zbo_mara as _Mc on $projection.matnr = _Mc.matnr



association [0..*] to Zbo_marc as _mrc on $projection.matnr = _mrc.matnr



{



ebeln,



@Search.defaultSearchElement: true



werks,



matnr,



@ObjectModel.association.type:  [#TO_COMPOSITION_ROOT]



_Mc,



@ObjectModel.association.type:  [#TO_COMPOSITION_PARENT]



_mrc



}

Child node ZEKPO created in the back end with the associated associations to the root node(ZBO_MARA) & parent node(ZBO_MARC)



 

Register the OData service in /iwfnd/maint_service.

 

To register the OData service we need to add the service follow the steps mentioned in the link
