I'm trying to find out what the difference is between messages M8 082-085 and M8 478-481 as the messages are the same. On searching I have found that M8 082-085 are for invoice and M8 478-481 are for Credit Memo. To prove this I have tried to replicate the messages in different scenarios. I'm able to verify that messages M8 082-085 are indeed for LIV when LIV amount is greater than tolerance amount versus the Goods Receipt amount. I'm however battling to prove whether the theory of messages M8 478-481 are for the credit memo process.
First question - Are messages M8 478-481 for the Credit memo process
Second question - If they are, then how do I replicate a scenario where these messages would appear?
Thanking you in advance for any assistance.
