Thanks.
I am creating a new data view.
The Planning Start Date for the data view will need to be recalculated annually.
The Planning Start Date in the Planning Book / Data View designer is used to determine the start of the planning horizon.
Txn /SAPAPO/SDP8B
To dynamically update the Planning Start Date field the User exit 'PDATE' should be used (at least this is what the SAP Help on the field states).
I don't see a PDATE user exit.
I need to understand where to find the Exit to update this field.
