SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20800 - Message class for CNV_20800

• Message number: 209

• Message text: Participating customers have different Authorization Group (KNB1-BEGRU)

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

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 'Authorization Group'. (This
is determined by the indicator 'Authorization Group', field KNB1-BEGRU).
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

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 Authorization 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 - before you continue with the conversion

• What is the cause and solution for SAP error message CNV_20800209 - Participating customers have different Authorization Group (KNB1-BEGRU) ?

  The SAP error message CNV_20800209 indicates that there is a mismatch in the Authorization Group (BEGRU) for the customer master data (specifically in the KNB1 table) between participating customers during a data migration or conversion process. This typically occurs in scenarios involving data transfer or consolidation where multiple customer records are being processed, and the system detects that the authorization groups assigned to these records do not match.
  Cause:
  
  Different Authorization Groups: The participating customers have been assigned different authorization groups in the KNB1 table. This can happen if the customers were created or maintained in different environments or if there were changes in the authorization group assignments.
  Data Migration Issues: During data migration, if the source data contains customers with varying authorization groups, the system will flag this inconsistency.
  Configuration Differences: There may be differences in the configuration of authorization groups across different company codes or clients.
  
  Solution:
  
  
  Standardize Authorization Groups: Ensure that all participating customers have the same authorization group. You can do this by:
  
  Reviewing the authorization group assignments in the KNB1 table for the affected customers.
  Updating the authorization group for the customers to a common value using transaction codes like XD02 (Change Customer) or through mass changes using transaction MASS or LSMW.
  
  
  
  Data Cleansing: Before migration, perform data cleansing to ensure that all customer records have consistent authorization groups. This may involve:
  
  Extracting the customer data to a spreadsheet for analysis.
  Identifying and correcting discrepancies in the authorization groups.
  
  
  
  Consult Documentation: Review the SAP documentation related to the specific migration or conversion process you are executing. There may be specific guidelines or tools provided by SAP to handle such issues.
  
  
  Use SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling authorization group discrepancies.
