problem during MIRO posting
While I am trying to do a MIRO posting for a purchase order for which GR based invoice is unticked. suppose the PO is for 100 quantity and net amount is Rs1000 . I have to do MIRO for 50 quantities . So I am changing the qty to 50 in item detail so the amount should automatically change to Rs 500 ,but the amount is remaining at Rs 1000. Actually at our client they got new user id .User is saying during his previous login the value was changing according to quantity .
Can anybody tell me how I will rectify it ? Any authorisation related things missing ?
