In this step, you organize the screen for entering or displaying characteristic values during line item entry/display. You do this by assigning a characteristics group to a record type.
If, for example, you assign a characteristics group to record type "F", then only the characteristics in that characteristics group will appear as entry options when a user is entering a line item for this record type.
If you have not assigned any characteristics groups to a record type, then users can enter/display all the characteristics for the operating concern.
You need to have defined a characteristics group containing the characteristic "Company code" as a required field. The company code for a line item must be known at the point when derivation occurs as a user enters that line item.
Assign the characteristics group to the desired record type.
