Account & & for deductions/cash discounts cannot be tax relevant

What causes this issue?

The system is trying to automatically post cash discount deductions or
unauthorized deductions to account &V1&. In company code &V2&, no tax
adjustment is defined for deductions of this kind (Customizing for
Financial Accounting is configured so that the net amount is the basis
for the cash discount). In this case, the account to which the posting
is made must not be tax-relevant.
