How to reverse ERS related goods receipt documents

[Grace_Li1]

Dears,

We met a ERS related problem. We used ERS Evaluated Receipt Settlement function, post goods receipt, and through APP "schedule supplier invoice jobs", to schedule ERS jobs, post invoice automatically by job.

But today, we found the purchase order is incorrect, need to reverse the invoice and goods receipt.

When we tried to reverse the invoice, we found the error message "M8.414", the message said, if you want invoice creation completely using ERS, then you must cancel the goods receipt and not the invoice document. ERS will then create the relevant cancellation invoice document for the cancelled goods movement". 

However, when we use APP "post goods movement" to cancel the goods receipt document, system also generated the error message "M7021 Deficit PU IR Quantity  XXXXX".

Could you please guide how to reverse ERS related goods movement document? Is it another APP? 

Thank you very much.

Best Regards,

Grace

Couple of ways are there to reverse ERS document
ERS invoices must be reversed by reversing the GR, not by canceling the invoice directly. Use the Post Goods Movement app or transaction MIGO. Select Movement Type 102 (Reversal of GR), Reference the original GR document, Ensure the quantity matches exactly. If you get M7021 Deficit PU IR Quantity, it means the invoice quantity has already been settled and the system blocks reversal.

To allow GR reversal even after invoice creation, you need to adjust customizing SPRO → Materials Management → Inventory Management → Goods Receipt → Set “Reversal of GR Despite Invoice” for Movement Type 102. This setting allows reversal of GR even if an ERS invoice exists. Check SAP Note 497178 explains this configuration.

Once the GR is successfully reversed, the ERS job will automatically create a cancellation invoice for the reversed GR. You do not need to manually reverse the invoice in MR8M.
