Here you can select the code for the number series you want the program to use when assigning numbers to a simulated production order. Click the AssistButton to the right of the field to see the number series, in the No. Series table.
If you want to use more than one number series for simulated production orders, you can set up a relationship between the relevant series in the No. Series Relationship table. This will allow you to use one code to represent two or more number series.
