Error translating the quantity to the CO-PA standard quantity

What causes this issue?

Your <DS:SIMG.SIMG_CFMENUORKEKE4MS>customizing settings</> in
Profitability Analysis (CO-PA) call for quantities to be updated in a
standard quantity field. An error occurred while the system was
populating the standard quantity field <ZH>&V3&</> for this document.
The unit <ZH>&V1&</> could not be translated to the standard unit
<ZH>&V2&</>.

System Response

The document cannot be processed further.

How to fix this error?

Check the unit that you entered (<ZH>&V1&</>).
For this translation to be possible, both units must be contained in
the <DS:SIMG.SIMG_CFMENUOLMSOMSC>table of units of measure</> and must
have the same dimension (not "dimensionless").
You may also want to check whether the rule for deriving the unit for
the CO-PA standard quantity field <ZH>&V3&</> was changed in
Customizing for CO-PA <DS:SIMG.SIMG_CFMENUORKEKEDR>derivation</>.
