Changing account assignment at invoice receipt (MIRO/MIR7)

Question

Hello gurus,
I have got two questions concerning changing the account assignment of a PO item at invoice receipt.
Example: We have a PO item with account assignment category K and non-valuated goods receipt. Now, after GR, we receive the invoice and want to post it using MIRO.
During this process we notice that the correct account assignment category would have been A. In MIRO we can change all accounting information (apart from the account assignment category). So we delete the assigned G/L account and cost center and enter the correct asset master number in the asset column. Then we post the invoice.
Result is that the invoice is posted to the asset, the vendor and the tax account. So, everything seems to be ok, except that the account assignment category in the invoice document is still K.
Now, my questions:
1. Is it allowed to change the accounting information as described, even if that means that the account assignment category is u201Cwrongu201D afterwards? I.e. is this a standard process?
2. This works fine using MIRO, but when we try it to use MIR7, when posting the invoice there is a cryptic workflow error message (Message no. 00398) stating something like u201CPlaceholder for batch input error text, this message is not output. Please notify system administration u2013 Problem with S.u201C [sic!]
Any ideas on this?
Thanks in advance

Hi Praveen,
no, there is no error in MIR7. But the invoice is not posted and the workflow shows the error message given in my original posting.
And the point is that I cannot change the K to A in MIRO or MIR7, but I can change G/L account, cost center, asset etc. So after I change it, I still have account assignment category K, but no G/L account and cost center given. Instead, there is only the asset number.
This looks a bit funny to me and I wondered, if this could lead to any problems, because something like that would not be allowed in the PO.
