SAP Note 28134 - MR01: Incorr. withholding tax base for credit memo

Symptom:

In table T059Q, the 'Net base for contributions' indicator is selected for the withholding tax base calculation. When you post a credit memo, the withholding tax base was calculated incorrectly (if it was not entered).
The tax amount was added to the gross amount instead of being subtracted. Another consequence was a negative withholding tax exempt amount.
Sympton during the document display:
A: The field value is too great. A display is impossible.
