OTL DBI to compare the run time reported time dependent details ( State, County, City ) with earlier

Summary

How to compare the run time reported dependent details with earlier submitted dependent details

Content

Hi,

There is a requirement to show warning message  to user on OTL Time Card submission page when the dependent details reported (State, County, City) are different than the earlier submitted dependent details (State, County, City).

I am able to fetch the earlier submitted dependent details (State, County, City) through value set calling method in the Time Entry Fast Formula.

But I am struggling to find the method or attribute to call in the Fast Formula for the dependent details (State, County, City) submitted during this transaction like other reported time. Also, how to identify if the dependent details submitted is for edited row of any already existing/submitted row, or its a completely new row.
