How To Fix CNV_20800164 - Participating customers have different Deletion flag (KNB1-LOEVM)

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20800 - Message class for CNV_20800

• Message number: 164

• Message text: Participating customers have different Deletion flag (KNB1-LOEVM)

Diagnosis
The system found that more than one old customer numbers are planned to
be merged to the Target Customer number as per the mapping. However, not
all the old numbers have identical master data settings. It was found
that old customer numbers have different <ZH>'Deletion Flag for Master
Record (Company Code Level)'.</>
This is determined by the indicator <ZH>'Deletion Flag for Master Record
(Company Code Level)' </>(field <ZH>KNB1-LOEVM</>).
The problem may occur due to merger of customers having different master
data settings and 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 customers have been made.
The respective customers are not used any longer and are meant to be
merged into a dummy customer.
Procedure
Analyze the situation and either change the mapping so that only
customers with identical master data settings are merged or decide to
ignore the message because one of the prerequisites described above
applies.
In case you decide to ignore the error irrespective of the above
mentioned cases, you should consider that <ZH>the target customer will
retain the 'Deletion Flag for Master Record (Company Code Level)' of the
old customer number on which priority indicator is set.</> The
post-conversion impact of this should be properly evaluated and the
inconsistencies that it may have post-conversion should be estimated at
this stage.

• What is the cause and solution for SAP error message CNV_20800164 - Participating customers have different Deletion flag (KNB1-LOEVM) ?

  The SAP error message CNV_20800164 indicates that there is a discrepancy in the deletion flag (LOEVM) for customer master records (specifically in the KNB1 table) among participating customers during a data migration or conversion process. This typically occurs in scenarios involving data transfer or consolidation, such as during a system upgrade, data migration, or when using SAP's Customer Migration Tool.
  Cause:
  The error arises when:
  
  Different customer records have inconsistent deletion flags. For example, one customer might be marked as deleted (LOEVM = 'X'), while another is not (LOEVM = ' ').
  The system expects all participating customers to have the same deletion status for the migration process to proceed smoothly.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Customers: Determine which customer records are causing the issue. You can do this by querying the KNB1 table for the relevant customers and checking their LOEVM values.
  
  
  Standardize Deletion Flags: Ensure that all participating customers have the same deletion flag. You can either:
  
  Change the deletion flag for the customers that are marked as deleted to match those that are not, or vice versa, depending on your business requirements.
  If a customer should be deleted, ensure that all related records are also marked accordingly.
  
  
  
  Data Consistency Check: After making the necessary changes, perform a consistency check to ensure that all customer records are aligned in terms of their deletion flags.
  
  
  Retry the Migration: Once the discrepancies are resolved, retry the migration or conversion process.
  
  
  Related Information:
