SAP ABAP - Custom Agent Determination Supplier Invoice Flexible Workflow Approval

-
Approval Supplier Invoice document (MIR7) using flexible workflow with custom agent determination.

Using custom agent determination for supplier invoice approval with flexible workflow in SAP involves several steps. Below is a step-by-step guide to help you set this up:

Step 1: Understand the Requirement

  • In my case, custom agent determination need to maintain with custom table. Below the custom table needs:


  • After create both of tables, need to create custom CDS view which will be used in custom logic apps code

  • First CDS View ZInvoiceWf 
    @AbapCatalog.sqlViewName: 'ZIWFINVOICE'
    @AbapCatalog.compiler.compareFilter: true
    @AbapCatalog.preserveKey: true
    @AccessControl.authorizationCheck: #CHECK
    @ClientHandling.algorithm: #SESSION_VARIABLE
    @EndUserText.label: 'Supplier Invoice Workflow'
    @VDM.viewType: #COMPOSITE
    @VDM.lifecycle.contract.type: #SAP_INTERNAL_API

    @ObjectModel.usageType.sizeCategory: #M
    @ObjectModel.usageType.serviceQuality: #A
    @ObjectModel.usageType.dataClass: #MASTER
    @ObjectModel.supportedCapabilities:
      [  #CDS_MODELING_DATA_SOURCE,
         #CDS_MODELING_ASSOCIATION_TARGET,
         #SQL_DATA_SOURCE                  ]
    define view ZI_SUPP_INV_WF 
      as select from zmmt007 as ZInvoiceWf 
    {
        key ZInvoiceWf.function as Function,
        key ZInvoiceWf.fundesc as FuncDesc,
        key ZInvoiceWf.app_lvl as AppLvl,
        ZInvoiceWf.bus_usr as BusUser    
    }

    Second CDS View ZI_SUPP_INV_REL_MAP
    @AbapCatalog.sqlViewName: 'ZIWFINVOICEREL'
    @AbapCatalog.compiler.compareFilter: true
    @AbapCatalog.preserveKey: true
    @AccessControl.authorizationCheck: #NOT_REQUIRED
    @EndUserText.label: 'Release Invoice Mapping'
    @VDM.viewType: #COMPOSITE
    @VDM.lifecycle.contract.type: #SAP_INTERNAL_API

    @ObjectModel.usageType.sizeCategory: #M
    @ObjectModel.usageType.serviceQuality: #A
    @ObjectModel.usageType.dataClass: #MASTER
    @ObjectModel.supportedCapabilities:
      [  #CDS_MODELING_DATA_SOURCE,
         #CDS_MODELING_ASSOCIATION_TARGET,
         #SQL_DATA_SOURCE                  ]
    define view ZI_SUPP_INV_REL_MAP as select from zmmt008 as ZInvoiceRel 
    {
        key ZInvoiceRel.zrel_group,
        key ZInvoiceRel.zrel_strat,
        key ZInvoiceRel.zfunction,
        key ZInvoiceRel.zsign,
        key ZInvoiceRel.zcurr,
        zamount
    } 

    @AbapCatalog.sqlViewName: 'ZVRBCO'
    @AbapCatalog.compiler.compareFilter: true
    @AbapCatalog.preserveKey: true
    @AccessControl.authorizationCheck: #NOT_REQUIRED
    @EndUserText.label: 'Invoice Account Assignment'
    define view ZI_INV_RBCO as select from rbco {
        key belnr,
        key gjahr,
        key buzei,
        key cobl_nr,
        wrbtr,
        sgtxt,
        txjcd,
        kostl
    }

    after create all CDS view need to publish all cds view to whitelisted object, to publish cds view


    Step 2: Create a Custom BADI Implementation

Create BADI implementation from sap fiori Custom Logic Apps:

Create new custom logic


After create, will show the custom logic page, in custom logic page go to Filter tab and add new filter workflowscenario = WS00800303 


add this code to custom logic code
    DATA:
