How to do to add a specific BAPI WBS Check betteen 2 systems via ALE
I am on the module TRAVEL MANAGEMENT (FI-TV) into the sap system DTM version ECC5 (for expenses). I wish communicate with the SAP system R/3 DGI version 4.6C via ALE and BAPI.
When I create the expense in DTM, I put a WBS and I want to do severals checks via ALE into the system DGI.
I have implemented the note 516109 into DGI to instal the bapi "BAPI_PROJECT_EXISTENCECHECK".But the link doesn't work from DTM to DGI.
Please could you help me ?
