Request ARCH tables usage
How are the tables OOTB archive tables KCRT_REQUEST_DETAILS_ARCH and KCRT_REQ_HEADER_DETAILS_ARCH used in the product? Is there any way to archive the request data using these tables? The data model guide mentions that these tables are used when the when a user changes the request type or request header type of the request. So are these temp tables used internally by product code? I don't see an admin report or product feature utilizing those for archiving the data as such. Any clarification is greatly appreciated.
Your conclusion from the PPM Help is correct: These tables are used to keep track of previous fields values when the request type of a request changes - their content is deleted when the original request gets deleted, and they should not be used for manually archiving requests data.
