change FI document type using substitution
In my current scenario to change the FI Document type posted through MIRO for a particular PO type...
I have created a substitution in GGB1 for a pre-requisite of PO doc type "ASD" and transaction "MIRO".
I have also activated it in OBBH for call point 1 - Document Header.
I want to substitute the FI document type to "Z1" for this particular PO type "ASD". I am not able to do it as it always post "RE" document once MIRO is executed.
Please suggest me if any other customizing/activision is required.....or we cant change the document type via substitution.
One last note, I don't want to change the standard MIRO code.
