1. Go to Supplier Invoicing work center
2. Select invoices and Credit Memos view
3. Search for the respective invoice ABC
4. Go to Exceptions tab
5. Error: 'Posting of invoice not possible due to error in financial accounting ; Referenced Purchase Order XYZ not found'.

Purchase Order XYZ's item was created with 'Expense' as its Item Type, but a Product ID was also included.

If you add a Product ID while using the Item Type 'Expense', the system will cross-reference and update the Item Type associated with that Product ID.

Consequently, the Item Type will automatically change from 'Expense' to either 'Service' or 'Material'. 

Do not include a Product ID when using the Item Type 'Expense' in your Purchase Order.

Instead, maintain a manual Description and a Product Category ID.

Existing exceptions in the Supplier Invoice can be accepted.
