Change Documents Migration

Hi All,

I have a scenario where I need to migrate the change document data from CDHDR, CDPOS from one system to another system. In my case, I have a downtime of around 20 hours to complete the migration. However, the table CDPOS has more than 5 billion rows and hence can't be migrated within the given time frame. Thus, I am planning to migrate the table during up time and have a few doubts on this table.

Are the entries in CDHDR / CDPOS always inserted or can existing data be changed somehow ?

If it is always inserted, then is the CHANGENR always the next number for a specific object ?

Kind Regards,

    No, not all changes are recorded in CDHDR - CDPOS.

    If a data element doesn't have the flag to register changes, no entry is made into CDHDR / CDPOS.
