SAP Note 26552 - Calculation key NA0 with incorrect base value

Symptom:

The American calculation key NA0 (ALTMIN Tax, wiht declining balance of 15%) was delivered with the incorrect base value 'Acquisition value' (01). Declining balance keys can only calculate correctly with the base value 'Net book value' (24).

Cause and prerequisites

Incorrect delivery

Solution
Advance correction: You can also use key M150 instead of NA0 which delivers the same result.
Change the base value on the detail screen of the calculation key NA0 to '24' with transaction AX01 and save it afterwards.
