How do I implement dynamic agent selection for supplier bank update workflow in SAP MDG?
Use a custom dynamic agent class that implements IF_USMD_SSW_DYNAMIC_AGT_SELECT and derive company codes from the BP change request, then filter the IAM approver list by company code, remove the request creator, and return the user-agent group for the workflow step.
SOLUTION SUMMARY · SHORT ANSWER
Use a custom dynamic agent class that implements IF_USMD_SSW_DYNAMIC_AGT_SELECT and derive company codes from the BP change request, then filter the IAM approver list by company code, remove the request creator, and return the user-agent group for the workflow step.
Dynamic agent selection for supplier bank updates in SAP MDG is typically implemented in a custom class that implements IF_USMD_SSW_DYNAMIC_AGT_SELECT. The supplied example class ZCL_MDG_DYN_AGNT_SUP_BANK_UPD reads the BP change request, derives company codes, filters the approver list by those company codes, removes the requester, and passes the resulting user agents back to the workflow step.
Process flow
- Implement a custom class that implements IF_USMD_SSW_DYNAMIC_AGT_SELECT.
- Read USMD120C to get the current change request creator and context.
- Create a model instance with CL_USMD_MODEL_EXT=>GET_INSTANCE for model BP.
- Read BP request data and derive company codes from BP_COMPNY or the bank UIBB field.
- Call your approver retrieval source such as ZCL_MDG_WF_APPROVERS_RETRIEVAL=>GET_APPROVERS.
- Filter the approvers by company code or REGION_ORG.
- Remove the requester from the final agent list.
- Populate CT_USER_AGENT_GROUP and clear CT_NON_USER_AGENT_GROUP when the step is a dialog approval step.
