End dating Benefits post Termination

Summary:

Hello Team,

There is a business requirement to end date benefits enrollment after few days post terminations. The Gap between end dating of benefits and termination date varies on case to case basis.

Currently, while I am evaluating the Termination life event after 60 days post termination, I am getting an error (Document attached capturing the case).

Can you please let me know incase we can create any custom logic for same to end date benefits enrollment for any number of days (Varies for each case)? Or is there any possibility to evaluate the life event for Default Benefits Relationship with Life Event effective date post termination.
