Reproducing the Issue

  1. Go to Supplier Invoicing work center.
  2. Go to Invoice Entry view, find a to be invoiced purchase order.
  3. Create a new invoice for it.
    In the new screen, you can see the due date is automatically proposed and grayed out.


You have maintained a payment term for the supplier of the purchase order, and defined the due date calculation rule for the payment term.


You can check the due date calculation rule for the payment term by following steps:

  1. Go to Business Configuration work center.
  2. Go to Implementation Projects view.
  3. Open Activity List.
  4. Open Fine tuning activity: Suppliers.
  5. Open Define Payment Terms for Procurement.
    Find payment term ABC, you can see the definition: Calculate due date based on *.

Due Date field is grayed out because system calculates according to the payment terms entered in the invoice.

In case you want to maintain a specific due date,  you need to remove the payment terms in the supplier invoice, then you will be able to manually enter the due date.
