In the during past month,as my work as RtR Front office I did not contact to other EtE processes much (PtP,OtC,HtR) and there is no issue talking about it.
However, I would like to mention the case below that I agree on the documents related to the booking in SAP should be attached for the purpose of review and to get details which in the past may have some transaction that the attached document is missing.
