AR Form Personalization Issue

Hi,

We have a Weekly AR cycle i.e. in current week, system should not allow users to enter any AR receipts with GL date which falls in prior week (even though AR and GL period are open)

So, we have created a Lookup and specified a start date and then through form personalisation we have restricted users from entering any receipts prior to the start date entered in that lookup.

Note:- Every week, our AR business users updates the start date in the lookup.

Now, the issue is if users are trying to query any of the existing old receipts and try to update DFF value or Comments field, system is throwing a error message (the message which we specified in our form personalisation).
