Suppliers shouldn't be able to enter negative values via credit memos when invoicing in BN

Is there a way to prevent suppliers from entering negative values ​​when creating a credit memo or correcting an invoice?

I'm only specialized on the FI side and ECC/S4 hana cloud public version for this topic but I've done some researches on the web and found something talking about "Custom Validation Rules".

Is it something you have heard of ?

Hello dear user,

And thank you for asking your question in the SAP Community blog.

Yes, you can prevent this phenomenom by making sure that the configuration for the document type does not allow the negative amount for the credit memo documents.

Here is where you can find it :

And then untick the negative values permission's option into the concerned document type :

I hope this will help solve your issue.

Best regards,

Jeremy
