In this step, you organize the screen for entering or displaying value fields during line item entry/display. You do this by assigning a value field group to a record type.
If, for example, you assign a value field group to record type "F", then only the value fields in that value field group will appear as entry options when a user is entering a line item for this record type.
If you have not assigned any value field group to a record type, then users can enter/display all the value fields for the operating concern.
You need to have defined a value field group.
Assign the value field group to the desired record type.
