MIRO vs FB60

Question

Hi all
I have a question regarding MIRO and FB60
The standard procedure to creating invoice is : ME21N --> MIGO --> MIRO
but in our office there was situation like this :
after MIGO, some user create invoice using FB60 so there is no link between PO and Invoice itself and the MIGO still open and waiting to be invoiced.
We don't know how it happen, not all the invoice treated like that
My question is: how to prevent users to create another invoice (duplicate invoice) using MIRO? Because the invoice already done using FB60
Thanks a lot

Della

Hi Della,
If there was some requirement then it can be handle, but principally this is not good practice, as you told that after MIGO, some user create invoice using FB60, see what entries you are doing.
Entry at MIGO:
Expense A/c    100
            GR/IR clr A/c   100
Entry through FB60:
Expense A/c    100
                       Vendor    100
In this case your user booking double expense one at the time of MIGO and other one is directly in FI by FB60. Furthermore Open was there in GR/IR clearing account.
If it was requirement, to book invoice through FB60 after MIGO, although it can be handle, so you can use MR11 to reverse the expense booked at the time of MIGO, in this case your stock value will be zero but the quantity will remain there, after that you have to adjust your stock value manually by MR21.
