If you are using fixed prices it is possible to have the frequency calculated automatically based on the chosen billing category. Have your administrator activate this setting in the 7.2.1.1 Administration Settings by checking "Calculate the Frequency from the runtime".
Examples:
| Billing Category | from | until | frequency |
|---|---|---|---|
| CPD | 01.01. | 16.01. | 16 |
| CPW | 01.01. | 07.01. | 1 |
| CPMo | 01.01. | 30.06. | 6 |
| CPY | 01.01. | 31.12. | 1 |
If the selected date range doesn't match the billing category you will receive an error message.
