SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20800 - Message class for CNV_20800

• Message number: 181

• Message text: Participating customers have different Customer group (KNVV-KDGRP)

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>Customer group</>. (This
is determined by the indicator <ZK>Customer group</>, field KNVV-KDGRP).
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>Customer group</> 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.

This error typically arises in scenarios involving data transfer, such as during a system upgrade, data migration, or when using SAP's Customer Migration tools.
  Cause:
  The error occurs when:
  
  Two or more customer records that are being processed have different values in the customer group field (KNVV-KDGRP).
  The system expects that participating customers should have the same customer group for the operation to proceed, but it finds discrepancies.
