Hi,

We are in ECC6 and we activated the Document splitting and we configured and activates the profit center accoutning with number ranges for actual documents but whenever we are doing the MIGO and MIRO there is no controlling and profit center document is generating and only accounting document is generating .

What is the reason for this can we cannot get these docuements from MM ?
