In my Invoice requisition app there are 3 tables i.e. Invoice requisition, Submissions, FMS. I need a query for my Invoice requisition table a field named ‘Invoice value’ where I have to put a query. The conditions are "Take user input for Invoice Value when Delivery Type is Partial. The Invoice Value should not be greater than the Basic final Revenue (Submissions) of the Contract ID(Submissions). Also, it should consider any previous Invoice Requisition(FMS) generated for the same Contract ID(FMS) "
THANKS IN ADVANCE.
