How to prevent past date selection on a GRC Control Attestation metric field?

[Sachin G K1]

Hi everyone,

I am working with GRC / IRM Control Attestations. I have added a custom question/metric of type Date called "Target Date".

I need to enforce a validation rule that prevents users from selecting a past date when completing the attestation. If they select a past date, it should clear the field and show an error message.

Thanks in Advance!!
