If you use optional fields and you set up any optional fields for automatic insertion on adjustments, they appear on the Optional Fields tab, along with their default values.
You can add or delete optional fields for the write-off batch. However, you can add only optional fields that are defined for adjustments.
When you process the write-off batch, Accounts Receivable assigns to the transactions all the adjustment optional fields that are marked for automatic insertion and any additional optional fields you specify on the Optional Fields tab.
The generated adjustments use the optional field values specified for the batch. If you deleted an optional field that was automatically inserted, the program assigns the optional field to the transaction, and uses the default value from the customer record, where the optional field is used in the customer record, or from the optional field setup record.
