External tax system has returned inconsistent total tax amount

What causes this issue?

During tax calculation, your SAP system retrieves tax amount information
from the system of your external tax partner. This message indicates
that the total tax amount returned from your tax partner does not
correspond to the sum of the tax amounts from all jurisdiction levels.

System Response

The data returned from the external tax partner system could not be
verified.

How to fix this error?

Please contact your external tax partner to verify that they sent the
correct total tax amount. If your tax partner did return the correct
total tax amount, then contact SAP to recheck the verification logic.
If your tax partner did not return the correct total tax amount, then
your tax partner should adjust their logic to ensure that he or she
returns the correct total tax amount.
