Problem
When creating a return and entering a PO number the items do not automatically appear in the list. The error message No Records Available shows up in the item list field.
Solution
What is causing the No Records Available error when creating a return?
The error message No Records Available, which causes no items to populate on a return, is likely because there is no bill associated with that purchase order.
In the Inventory or Purchasing module, click on Purchase Orders.
Click on the PO number for the PO with the error.
Click on Documents under the heading.

If there is no Documents link, or no Bill showing in the Documents, you'll need to manually create a bill.
Once the bill is created, try the return again.
To avoid this problem in the future, consider enabling the auto creation of bills.
If there is a bill showing, but the error remains, contact technical support.
