If purchase order lines are created from the "grouping workbench" function , the minimum "expected receipt date" (EXTRCPDAT field) is equal to the order date plus the lead time from the price list, the product-site record, or the product record, in that order.
If the user enters an earlier “Requirement date”, it is not retained.
It would be useful to be able to retain this “Requirement date” in the “expected receipt date" of the order lines, even if it is earlier..
