How To Fix CNV_20800154 - Participating customers have different Country key (KNA1-LAND1)

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20800 - Message class for CNV_20800

• Message number: 154

• Message text: Participating customers have different Country key (KNA1-LAND1)

Diagnosis
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 <ZK>Country Key</>. (This is
determined by the indicator <ZK>Country Key</>, field KNA1-LAND1).
This may lead to inconsistencies in some applications related to target
customer data.
System Response
<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.
Procedure
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 </><ZK><ZH>Country Key</></><ZH> 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.
