in Time Entry Rule formula, how to identify if any entries were deleted

Summary:

We have requirement of freezing the timecard for certain periods. As there are different period combinations for different employees. But we just follow only weekly time cards for ALL.

One particular group, on 12th of the month, the previous months timecards to be frozen for employee edits.

The 31st of the month may fall within one week timecard, means 29-Jun-2026 to 5-July-2026.

on 12th July, the timecard edit should not be allowed for only July. i.e. 29 & 30 June dates within same timecards to be NOT editable.

We have written the TER formula & its working well for NEW/EDITED referring the input - OraHwmTcRowStatus.
