The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
According to the mapping, you want to merge two or more old customer
records into one target customer record. However, not all the old
records have identical master data settings: It was found that old
customer records have different values for Central billing block for
customer. (This is determined by the indicator Central billing block for
customer, field KNA1-FAKSD).
This may lead to inconsistencies in some applications related to target
customer data.
<ZH>Error</>
From a technical perspective, this message can be ignored. This may make
sense in the following cases:
No postings to the respective customer records have been made.
The respective customer records are not used any longer and are meant to
be merged into a dummy record.
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 Central billing block for customer 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 - <ZH>before</> you
continue with the conversion.
