When manually entering incoming MM invoices our process looks so that if GR is missing for invoice, it gets parked and waits for GR. After GR is done, invoice handler clicks on a button "Update allocation" and after this he/she is able to post invoice document.
Now we are creating functionality which will post invoice documents in background using FM 'MRM_INVOICE_ALLOC_UPDATE'. But it does not seem to be wokring as expected !!
Have anyone done this "Update Allocation" in the background via program ? Can you please advise me on this problem? I will highly appreciate it.
