Assignment set with Criteria for a BEE

I have created an assignment set with the following criteria:

10          &ASG_EMPLOYEMENT_CATEGORY = 10 Month Employee

20     AND     &PER_PERSON_TYPE     Like     Employee%

Save and Generate.

Then I create a Batch Element Entry, using this assignment set, with an Element Name of Regular, post hours save and process.

Once the Create Batch Lines process completes successfully, open Element Lines in the batch to confirm and there is nothing there.

What am I missing? Please.

I use this alot for patch testing the entire population, but now I need to narrow it down by the Employee Category.

Thanks

Carrie
