How to check detailed calculations for payment schedules
Path in CC5: Contracts - Edit
When clicking View detailed calculations in the Payments section below the payment schedules, you get an overview of your combined obligations and receivables for this contract.

Click this link to open a detailed list with the payment calculations with both gross and net amounts. The calculation lists on the Overview tab contains obligations/receivables (dependent on what you've selected on the payment schedule) and outgoing cashflow. Click "+" to expand the years and view the amounts per month.
Tip!
Click "+" next to Title to expand the complete list, not only single years.
Click Show net amounts if you want to view net receivables and obligations and net cashflow. Net means in this context: Sum receivables minus obligations.
If Currencies are activated in your solution, you can also check the amounts in other currencies. The amount is calculated based on the currency rate in your system.

The Cashflow tab lists outgoing and incoming cashflow per year for the various payment schedules.
Also here, you can select net amounts and currencies.
