Need user exit and runtime structure to get all the unsaved entries in CAT2

Hi Friends

As per our requirement, we need to compare all the entered hours from CAT2 vs Project level assigned hours.

If user save the record in CAT2, then no problem.I can get the records from CATSDB table.If user enter the record in first week and goes to next week without saving time entries in CAT2, Runtime structure catsd_imp-sumdays in user exit CATS0009 shows the current screen hours only.But I want to get all the entries entered in CAT2(Unsaved records).Is there any other user exit or badi available to get this functionality.

Thanks in advance...
