What causes this issue?

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 Industry key. (This is
determined by the indicator Industry key, field KNA1-BRSCH).
This may lead to inconsistencies in some applications related to target
customer data.

System Response

From a technical perspective, this message can be ignored. This may make
sense in the following cases:

The respective customer records are not used any longer and are meant to
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 Industry key 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.

• What is the cause and solution for SAP error message CNV_20800192 - Participating customers have different Industry key (KNA1-BRSCH) ?

  The SAP error message CNV_20800192 indicates that there is a mismatch in the Industry key (BRSCH) for participating customers during a data migration or conversion process. This error typically arises in scenarios where multiple customers are being processed, and the system detects that the Industry key for these customers does not match.
  Cause:
  The primary cause of this error is that the participating customers in the migration process have different values for the Industry key (BRSCH) in the KNA1 table (which contains general data for customers). This inconsistency can occur due to:
  
  Data Entry Errors: Different industry classifications may have been assigned to customers erroneously.
  Different Business Units: Customers from different business units or regions may have different industry classifications.

  Updating the industry key for some customers to ensure consistency.
  Deciding on a common industry classification that all participating customers should adhere to.
  
  
  
  Data Cleansing: If the data is being migrated from a legacy system, consider performing data cleansing to ensure that the industry keys are consistent before migration.
  
  
  Re-run the Migration: After making the necessary adjustments, re-run the migration process to see if the error persists.
