Change the base system calculation unit

The Base System Calculation Unit is used across the system for different calculations, including payables and receivables. By default, it is set to source word; however, you can change it to another unit that better suits your needs.

Go to the Configuration menu > General Configuration > Settings > Defaults tab.
Scroll down and click the Edit button at the bottom of the page.
Go back to the top and click the Change button in the Base System Calculation Unit section.
Select the required calculation unit from the drop-down list.
Decide whether you want to Reevaluate exchange ratios for calculation units automatically.
If you check this box, the system will recalculate the payments for vendors with non-standard contracts (e.g., paid per the performed task). For example, if your default calculation unit is source word and you have changed it to 1 hour of work, the system analyzes how many hours it takes to complete the task and provides the future charges based on the new calculations.
Click the Save button.
