Invoice Reduction: No separate document type exists for invoice reduction

Question

Hi,
I am posting a document for Invoice Reduction and getting the following error message. I have seen the document types in OBA7 T-code. What is the document for Invoice reduction, is it same as Credit memo or different one?
Can you Pls guide me to complete the transaction successfully.
Error Message:
No separate document type exists for invoice reduction
Message no. M8507
Diagnosis
You want to post an invoice that has been reduced. This results in two FI documents being created. You require different document types to process both FI documents correctly.
System response
The invoice cannot be posted.
Procedure
Your system administrator must enter a separate document type for invoice reduction with transaction MIRO in Customizing for Logistics Invoice Verification.
Regards
Hari.

Hi Hari,
Procedure for posting the Invoice Reduction :
(1) Enter the T.Code MIRO - Select the Transaction as Invoice only.
(2) Give the reference number ( Example PO Number) for which you want to create an Invoice.
(3) In the Display Variant, Select Invocie Reduction.
(4) Maintain the required details and post the Invocie.
Example: Invoice Reduction due to Quantity Variance:
PO: 100 nos @ 10 EUR/No
GR: 40 nos
Invoice: 40 nos @ 12 EUR/No = 480 EUR
When you enter Invoice,
Order Qty            Order Amount         Invoiced Qty        Invocied Amt
40                        400
Select Reduce Invocie in the Display Variant.
Enter the Quantity and Amount stated in the Invocie  in the fields Invoice quantity acc. vendor and Invoice amount acc. vendor.
Order Qty            Order Amount         Invoiced Qty        Invocied Amt
40                        400                          40                        480
When you post the Invocie, Purchase order history will be updated as follows:
                           Quantity           Value
Total Delivered    40                    400
Total Invoiced     40                     400
Accounting Documents:
GR:
Stock Account = 400
GR/IR Clearing Account = 400(-)
Invoice:
Vendor Account = 480(-)
GR/IR Clearing Account = 400(-)
Invoice Reduction Clearing Account = 80(+)
Automatic Credit Memo:
Vendor Account = 80(+)
Invoice Reduction Clearing Account = 80(-)
Thanks
