We are currently using BAPI 'BAPI_PROJECT_MAINTAIN' to handle any changes in a project i.e changes in WBS element hierarchy.
For a single WBS element hierarchy change, I have to pass in all the Project info ( With all the WBS hierarchy within the project ) when using BAPI_PROJECT_MAINTAIN.
Is there any SAP provided BAPI that we can use to handle hierarchy changes by just using the changed WBS hierarchy values?
