How To Fix CNV_20800153 - Participating customers have different Industry code 1 (KNA1-BRAN1)

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20800 - Message class for CNV_20800

• Message number: 153

• Message text: Participating customers have different Industry code 1 (KNA1-BRAN1)

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>Industry code</>. (This
is determined by the indicator <ZK>Industry code</>, field KNA1-BRAN1).
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>Industry code </>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_20800153 - Participating customers have different Industry code 1 (KNA1-BRAN1) ?

  The SAP error message CNV_20800153 indicates that there is a mismatch in the Industry Code 1 (KNA1-BRAN1) between participating customers during a data migration or conversion process. This error typically arises in scenarios where multiple customer records are being processed, and the system detects that the industry codes for these customers do not match.
  Cause:
  The primary cause of this error is that the participating customer records have different values in the Industry Code 1 field (KNA1-BRAN1). This can happen due to:
  
  Data Inconsistency: The source data may have been entered inconsistently, leading to different industry codes for customers that should be treated as part of the same group.
  Configuration Differences: Different configurations or settings in the source systems may lead to different industry codes being assigned to similar customers.
  Migration Logic: The logic used in the data migration process may not account for variations in industry codes, leading to conflicts.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Customers: Determine which customer records are causing the issue by checking the logs or error messages that accompany the CNV_20800153 error.
  
  
  Review Industry Codes: Examine the Industry Code 1 (KNA1-BRAN1) values for the identified customers. You can do this by querying the customer master data in the source system.
  
  
  Standardize Industry Codes: Decide on a standard industry code that should be used for the participating customers. This may involve:
  
  Updating the industry code in the source system to ensure consistency.
  Mapping different industry codes to a single standard code during the migration process.
  
  
  
  Adjust Migration Logic: If necessary, modify the data migration logic to handle the differences in industry codes appropriately. This may involve creating transformation rules that standardize the industry codes during the migration.
  
  
  Re-run the Migration: After making the necessary adjustments, re-run the migration process to see if the error is resolved.
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like SE16 or SE11 to view and analyze the customer master data (KNA1 table).
  Data Migration Tools: If you are using SAP's data migration tools (like SAP S/4HANA Migration Cockpit or LSMW), refer to the documentation for specific guidelines on handling industry codes.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or solutions related to this error message.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to resolve it.
