We are version 10 S3, and have PR05 social sec & medicare deductions set to priority 1, federal a priority 2, states a priority 3. If you are currently using these priorities for other deductions, such as benefit and voluntary deductions, you may need to re-visit those deduction priorities also, to make sure the deductions you want to be withheld first will be. You will need to run PR115 to update the priority on the PR14 employee deductions and you may need to change the More tab for Priority from a 1 to a 2. I would suggest doing this in your TEST environment first. Before making the PR05 change/PR115 update, I would extract the deduction codes you are changing from the EMDEDMASTR table. Then, once you make the change, you can extract the data again to confirm it updated the records/fields you were expecting. In prior years, we did have some issues with the PR115 More tab, but I believe those have since been resolved.
