2528142 - Unable to Add Material to a Supplier Invoice


You have blocked a Material from Purchasing Processes in the Material Master Data but when you try to create a Supplier Invoice without Purchase Order you still can add the same in the Document.

Reproducing the Issue

  1. Go to Supplier Invoicing Work Center.
  2. Go to New Invoice without Purchase Order View.

Here you are still allowed to add any material even if the same has the Purchasing Process blocked in the Material Master Data.


This is because blocking the purchasing process will only prevent you from adding the Material in a Purchase Order, Shopping Cart, etc.


An alternative is to descope the Question 'Do you receive invoices without reference to other purchase documents?' from the Business Configuration.

You can find it going through the below steps:

  1. Go to Business Configuration Work Center.
  2. Edit the Project Scope.
  3. Go to Step 4-Questions.
  4. Expand the below path.

Purchasing > Supplier Invoicing > Supplier Invoices and Credit Memos > Group: Supplier Invoicing Types > Do you receive invoices without reference to other purchase documents?

This question allows you to create Supplier Invoices without any reference. Once this is descoped, no one in the system will be able to create Invoices without a Purchase Order.
