Change document tables
The change document tables are as follows:
CDHDR - Change document header table
CDPOS - Change document items table
Activate change document history for a specific field
In order to activate the change history for a specific field simple check the 'change document' checkbox within the data element.
Add entries to Change Document tables
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

Press the ‘Generation info’ button
Step 4 (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 5 (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.
Create Change Document History functionality for a new table
If you want change history on one of your newly created Ztables or infact an SAP table that
does not currently have it you will need to implement the following steps:
Step 1 (Execute transaction SCDO)
Step 2 (Click the create button and enter name!)
Note: Will probably get the message ‘Change document object ZNEWCH is not in your namespace. Do you still want to create the object?’. Just click yes!
Step 3 (Enter table details )
Enter table name of which changes need to be tracked and press insert!
Step 4 ( Save )
You should now see the following screen, Press the save button, followed by the
