That's exactly one of the quite common requirements that cannot be fulfilled with HISTORY tables.

 

Given the other thread I saw from you, I assume you just "discovered" history tables and now try to match it to application level requirements (change history of records, application level validity, compare history with current, etc. ... ).

 

To start of you may check When I traveled through time using SAP HANA!! and especially the discussion in the  comments section.

 

If time related data processing is relevant to your application, make sure to read the book (link in the above discussion) of Snodgras and "bi-temporal-data".
