HI @EmadK
Is the [Student ID] column, ID column in the Student’s table? If so, maybe instead of [Student ID] in your Request Pickup action try to use [_THISROW] combination.
@EmadK it may sound funny but maybe try to rename (just for testing) the [Student ID] column in the destination table. I had few situations where renaming columns solved my problems.
When I look at this what you attached I cannot see the error -after whole day on platform my mind is a bit tired it can be a reason as well ..
*maybe you could also share how those tables’ structures look like?
BTW I am sure there are other users who could help you too. Let’s wait for them.
