This activity is used to enter combination types to be used with a particular invoice type. A combination is entered by combining the invoice type with a numeration group and a branch.
For supplier invoice types, it is only possible to assign a specific number series in combination with a branch ID whereas for customer invoice types you can assign a number series in combination with a branch ID and a numeration group ID.
Invoice types must exist in order to perform this activity. Before you can specify a numeration group or branch, they must be defined in the appropriate basic data window (either the Numeration Groups window in IFS/Invoice, or the Branches window in IFS/Enterprise).
The correct number series entered with the combination types will be used when you are entering an appropriate invoice type, matching with the invoice type combination (invoice type + numeration group + branch) defined in this window.
