What causes this issue?

The <DS:DE.KSCHA>condition type</> has been set defectively for the tax
calculation. Typical errors are for example, the use of an
<DS:DE.KOZGF>access sequence</> when you are using a base amount, or
the non-assignment of an <DS:DE.KOZGF>access sequence</> when using a
tax item. You must ensure that a base amount cannot be set as
<DS:DE.KNTYP>condition category</> Tax, whereas a tax item always
requires the condition category Tax.
