I am trying to configure DDF in SAP Customer activity repository system. Prerequisite for DDF is to configure DRF replication for master data from SAP ERP system to SAP CAR DDF. we are already using SLT replication for master data from ERP to CAR, then is it necessary to have DRF replication again to configure DDF module in CAR? If DRF replication is required then is it necessary to have PI system? Few of the DDF configuration steps are mentioned below
Define the custom settings for data replication (transaction DRFIMG).
Assign a business system, a logical system, and an RFC destination to perform the initialization of data transfer.
while assigning business system in DRFIMG t-code, I am getting below error message.
Message no. LCR010
The application programming interface of the System Landscape Directory triggered an exception.
Contact SAP Support.
Please help me to resolve this issue. If possible please provide the documentation on DRF replication from SAP ERP to SAP CAR.
