Thank you Sivakumar for the details. Unfortunately, there is not First of next pay period code and it has only First of next month. At the moment we are using the element entry validation only and user experience is not that great as it validates the logic after submitting the transaction, but this is what best we could do…

There are only 7 different options in the Individual Comp Plan payment start date LOV and none are based on pay period so we cannot derive First of Next pay period.
