Let's assume you insert a value for an invoice in the Line item data section or edit a value.
If you want to insert or select a value in a line item column, only certain values are displayed. The values displayed are values that are valid for the field.
In this case, your administrator has defined a so-called dependence.
Things to know about dependent fields (dependency definition)
With an administratively defined dependence, certain fields are set in relation to each other. The values available in the fields are therefore only valid in this specific constellation.
If you have any questions or change requests, please contact your administration.
