determined by the indicator Tax Number 4, field KNA1-STCD4).
This may lead to inconsistencies in some applications related to target
customer data.

sense in the following cases:

be merged into a dummy record

How to fix this error?

Analyze the situation, and either change the mapping so that only
customer records with identical master data settings are merged, or
decide to ignore the message because one of the special cases described
above applies.
If you decide to ignore the error even though none of the special cases
described above applies, consider that<ZH> the target customer record
will get the Tax Number 4 of the old customer record for which priority
indicator is set. </>Make sure to evaluate the impact of this decision -
for example regarding potential inconsistencies and required follow-up
activities - before you continue with the conversion.
