Hello @ravindar.singh,
From my understanding of your problem,
you could try to check if there is values in the column first then
create List as `Black list’ to save the Booking ID value at it.
after that do for each item in Datatable and delete any row that has Booking_Id value in the list ``BlackList.
@AAydi I can do that but problem still stays how to remove rows or create DT with booking group which have no notes.
I found a simpler solution I have uploaded a .xmal for reference.
