IR should not post if GR reversal (MBST) exists

[Former Member]

My scenario is this. I am posting an invoice using MIRO against a PO, in which the GR was received using MIGO and then reversed using MBST. The invoice will post in this scenario, but I don't want it to. There isn't a valid GR for this PO since it had been reversed. Is there any way to block this? I would appreciate any help/suggestions you can give. This is particularly dangerous with our EDI transactions.

Hi Rhona,

Go to tcode OMRM, maintained message 088 with Error Message. This will prevent Invoice being created with GR reversal.

Thanks.

MR8M will not allow me to cancel a material document. The error message is "Invoice document 5xxx does not exist". It is looking for an invoice document, which is only created after MIRO is executed and the IR is posted. I am trying to find a solution which will block the IR from being posted, if the GR has been reversed. In other words, MIRO will not allow the posting of an IR if the GR does not exist, but it will allow it if the GR has been reversed.

Hi,

I faced the same issue. Have you got the solution?

Thanks.

Yes, when the material document is created (MIGO), an accounting document is also created which DR the expense and CR the GR/IR. However, this accounting document cannot be reversed using FB08. The error message is "Not possible to reverse the document in financial accounting". Anyway, the GR is being reversed by someone in the warehouse, not in finance. When using the transaction MBST, it reverses the material document and creates a new material document that references the old document. At the same time, it creates another accounting document that DR the GR/IR back and CR the expense. This document doesn't reference the original accounting document, however, and if you then try to enter an invoice using MIRO, the original GR will appear and the invoice can match it and post to it. This creates an accounting document that DR the GR/IR, and CR the vendor. Now, the entries for this PO are as follows:

1st GR:

DR expense

CR GR/IR

Reverse GR:

DR GR/IR

CR expense

Invoice:

DR GR/IR

CR vendor

This leaves the GR/IR with 2 DR and only 1 CR. I am trying to find a way to circumvent this from happening. When an EDI document comes in, it will post to this PO without realizing that the GR had been reversed.

Does anyone know of a way to prevent this?

hi rohan,

When u reverse the Material document through MR8M, It will reverse FI document automatically.

No need to reverse the FI document through FB08.

Yes, I used MBST because at the time there wasn't an invoice posted, just the material document for the goods receipt. So the PO History shows movement types of 101 for the quan received and 102 for the quan reversed. Then an invoice came in and by using MIRO, I was able to post this as if there was a valid GR on this PO.

Well, as you know that when a GR happens, both Material and FI documents get created. So if you just reverse the Material Doc, from a finance perspective, GR did happen, so IR can happen. However - if you reverse the GR Financial Doc also (You can use FB08), that would reverse the GR financial doc and IR would not happen.

Hope that helps..

Is there any particular reason you did it through MBST rather than by MR8M. If you do it by MR8M, you wouldn't come across this scenario as it would reverse both MM and FI documents created during GR.

Hope that helps.
