2606439 - Invoice reversal - not authorized to use MR8M

In your Cloud environment, you are trying to reverse a Supplier Invoice using the webgui tile 'Create Supplier Invoice - Advanced', but you run into an error stating 'You are not authorised to use transaction MR8M'.

•  SAP S/4HANA Cloud All versions. 

1. Open the APP 'Create Supplier Invoice - Advanced'.
2. Enter a Company Code.
3. Click on 'Other Invoice Document'.
4. Enter the invoice you want to reverse and the year. 
5. Press Continue.
6. Click on 'Reverse'. 
7. The error is raised.
   

The 'Create Supplier Invoice - advanced' tile is the webgui version of the backend transaction MIRO. When a document is reversed from MIRO, the system checks if the user has authorisation to run the reversal transaction MR8M.

In a Cloud environment, this is an incorrect procedure for reversing an Invoice.

An Invoice Reversal should be carried out via the APP 'Supplier Invoices List' as documented in the SAP Best practices, for example scope item J45.
