Prefix in corrections of ERS invoices (self-billing for consignment)

[j_madariaga]

Dear gurus,

We are trying to implement the functionality for correction ERS invoices. Concretely, we would need the correction for the invoices to include a prefix ("C") with a reference to the original invoice.

That is to say, if the original invoice shows in reference field "AB000120000059", where AB0001 is the number group (assigned with transaction J1AB; customizing: "Create ERS invoice number ranges") and 20000059 the corresponding number in the range defined for the corresponding number group (which, simultaneously has been assigned in field "Tax code 4"/view "control" in the material master data for the vendor.
Then, the correction invoice should have reference field "CAB000120000059".

Our attempts include:

- The creation of a new document class for the correction ("Define Document Classes")
- Assigning the document class to document types: although we are not sure about it. Which type should be assigned? KR-Vendor Invoice- and KG-Vendor Credit Memo?
- Assign number ranges to correction ERS invoices, including the new document class for corrections, the number group and the prefix

Unfortunately, it is not working properly, as the correction invoices do not include the prefix and the reference.

Lastly, just a comment: these invoices and corrections are created with transaction MRKO (as it corresponds to consignment materials).

Could anyone give us a clue of how to proceed, please?

Thanks in advance.

Best regards,
J

In MRKO you settle movements and create an invoice for that. There is no cancellation feature for this invoice, it is always a new invoice and the only reference is the movement. There is no reference to an earlier invoice. read also OSS note 356130 - MRKO: Reversing the documents and 80083 - Consignment settlement: Reversal

I guess that this the case. Firstly, we transfer the material from vendor ownership to our own material (material movement 411-K). Then, the invoice is created with MRKO transaction. Later, the material movement is cancelled with a reversal (material movement 412-K).

If we execute transaction MRKO, a new document is created with a negative quantity and amount. As you stated, there could be a mix of different receptions and reversals (although in our case we are completely sure that the correction corresponds to that invoice, as there is only 1 invoice and 1 reversal). But is there any possibility for creating correction invoices with reference for ERS with consignment? Or, otherwise, that option is only available only for ERS without consignment (that is to say, for transaction MRRL)?

Thanks and regards

How do you know it is a correction what you do in MRKO?

Another execution is just another settlement, can be a mix of cancelled goods issues and new goods issues.
