Hi,
With your screen - you are trying to create service order with PO document type NB with item category D and account assignment category K.You have following options:
Option-1:
If you are just creating service order with service master /service text without entering any value in "Limit" TAB of Purchase order in Item details, then you can do service entry sheet (ML81N) WRT service order for planned value with service master(activity number) or service text entered in "Service" TAB.
Option-2:
If you are just creating service order with service master /service text with entering value in "Limit" TAB of Purchase order in Item details,then you can do service entry sheet (ML81N) WRT service order for planned value with service master(activity number) or service text entered in "Service" TAB and also can do service entry sheet (ML81N) for Unplanned Value with Value available in "Limit" TAB.
