Change Documents
A change document logs changes to a business object. The document is created independently of the actual database change.
For changes to a business object to be logged in a change document, the object has been defined in the system as a change document object. The object class is the name under which a change document object is created. The object class in SAP Supplier Relationship Management (SAP SRM) is BBP_PRODOC.
The change document header contains the header data of the change to an object ID in a particular object class. The change document number is automatically issued.
The change document item contains the old and new values of a field for a particular change, and a change flag. The change flag shows that data has been updated or inserted.
The change document number is issued when a change is logged, that is, when the change document header is created by the change document creation function module (function group SCD0). The change number is not the same as the change document number. The change document number is issued automatically when a change document is created for a change document object. The change number is issued by the user when changes are planned. The same change number can be used for various change document objects.

new values of the item, who made the change, and when the change was made.
