SAP Message 56794 - You cannot delete receipts that have been paid by your company!

Diagnosis
You have marked a receipt, with expense type 'paid by company',for deletion in the credit card data document buffer. Receipts withthis expense type cannot be deleted.

System Response
You cannot delete this receipt. The System only allows you to deletereceipts that you have paid (in other words receipts that debited theemployees account and not the company account).

Procedure
Since the complete transaction amount was invoiced to the company bythe credit card provider, the full amount must be assigned to thecorrect trip by making a posting in Travel Expense Accounting.
If a credit memo exists for the debit, both of these should be assignedto the same trip.
If the receipt should not be assigned to you, contact your expensesclerk or system administrators.
