2 invoices generated for same material document via MRER

[Ramesha]

Hello MM Gurus.

I'm facing an issue while executing MRER transaction, SAP System is generating duplicate invoices for material document. For example : 2 invoices generated for 1 material document.

is anyone facing same kind of issue? is this SAP functionality?

How to prevent this issue in SAP ? Please help with your ideas/experience

Thanks

Your post is confusing me.  There won't be any material document for a credit note.  Only an accounting document (financial posting) will get generated crediting the Payer.  Please share the screen shot of document flow from the origin sale order for better understanding.

The issue is purely MM related . Goods receipt is done for scheduling agreement and we are doing automatic invoice (ERS) via MRER. system is allowed to executed MRER twice for 1 material document and generated 2 invoice documents for same material document.
