Ben Admin Issue - Plan Type XX entries not found in the benefit program

Hi,

We are at PeopleSoft HCM 9.0.

We got the below Error during our Ben Admin Process Run for one of the Employee.

Schedule ID: EM (Event Maintenance)

"Plan Type XX
entries not found in the benefit program YYY"  

For now, we have marked that event as closed and restarted the process.

I could see that the Plan Type XX is not available in the Benefit Program: YYY in the benefit Program Definition and there is no active enrollment for that plan type in Base Benefit Table for that employee.

But in the BAS_PARTIC_PLAN i could see an entry for plan type XX with Coverage Elect as 'E'.
