Percentage load on vendor/order records
On the screen for Vendor account details: Develop a data field entitled Overheads, with an input box that can take a percentage. This percentage indicates the percentage with which the value of each order linked to the vendor should be loaded automatically, with an override facility on the order record.
On the screen for creating a PO Line: Develop a data field entitled Overheads, with an input box that can take a percentage. This field should be populated automatically from the Overheads field on the associated vendor record, loading the value of the order with the percentage, with an override facility of the data in this field on the order record.
Additional suggestion: It is suggested that the overhead percentage should be calculated on the discounted amount, i.e. the Discount field should be effective FIRST, and the Overhead field should be effective SECOND.
