Optional fields are company-defined fields that can be added to any of the transaction-entry screens and to transaction detail lines if you use Transaction Analysis and Optional Field Creator.
Optional field entries can flow from requisitions and purchase orders to the associated receipts and invoices if you use the same fields for all the transaction screens.
You use the Optional Fields tab in a transaction-entry screen to enter information that applies to the transaction as a whole (header information). Optional fields on detail lines apply only to the single detail line. Changing the information in any of these fields has no effect on the transaction.
If Accounts Payable invoice header and detail optional fields are the same as those used in Purchase Orders invoices, the optional field information can be passed automatically to Accounts Payable.
If General Ledger transaction details optional fields defined for the General Ledger accounts match the transaction header and detail optional fields used in Purchase Orders invoices, the optional field data can be passed automatically to General Ledger (depending on your optional fields settings).
