Adding entries to Change Document History CDHDR & CDPOS tables using associated function module manually

When adding entries manually to the change document history tables(CDHDR, CDPOS) you will need to find the actual function module used by the SAP transaction to create these entries! This can be done as follows:

�        Step 1 (Execute transaction)

Execute transaction SCDO

�        Step 2 (Select required object)

Place the cursor in the required entry (i.e. GMGRANT) and go to the menu option: Change doc.object->Display

�        Step 2 (View generation info)

Press the 'Generation info' button

�        Step 3 (Retrieve update function module )

The following screen will be displayed showing various information, including the 'update function module' (i.e. GMGRANT_WRITE_DOCUMENT). This can then be viewed via SE37 or SE80 like any other function module.

�        Step 4 (Executing the function module)

If you want to know how the function module works and how to populate its parameters, then it is a good idea to put a break-point within the FM code and then execute the transaction which creates the change history entry. You will then be able to see what the transaction passes to the FM and replicate it.
