AP invoices and credit memos are considered incomplete and cannot be approved until they have been coded. Also, if you require attachments for each AP invoice in System Administration > Maintain Lookup Tables - Business Constants, they remain in this To-Do List Activity until an attachment has been added. To be coded, the line items on an AP invoice must be assigned to a GL account for expenses. It is possible to complete the Receive Invoice task without coding them.
Once an AP invoice or credit memo is received and coded,
it can be accessed in the Approve
Invoices To-Do List Activity.
