How To Fix CNV_20900187 - Participating vendors have different Deletion flag (LFB1-LOEVM)

CNV_20900187 - Overview

• Message type: E = Error

• Message class: CNV_20900 - Message class for package CNV_20900

• Message number: 187

• Message text: Participating vendors have different Deletion flag (LFB1-LOEVM)

Diagnosis
According to the mapping, you want to merge two or more old vendor
records into one target vendor record. However, not all the old records
have identical master data settings: It was found that old vendor
records have different Deletion Flag for Master Record. (This setting is
determined by the indicator 'Deletion Flag for Master Record (Company
Code Level)', field <ZH>LFB1-LOEVM</>).
The problem may occur due to merger of vendors having different master
data settings and this may lead to inconsistencies in some applications
related to target vendor 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 vendor records have been made.
The respective vendor 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 vendor
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 vendor record will
get the Deletion Flag for Master Record (Company Code Level) setting of
the old vendor record for which the 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.

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

CNV_20900187 - Details

• The SAP error message CNV_20900187 indicates that there is a discrepancy in the deletion flags (LOEVM) for participating vendors in a data migration or conversion process. This typically occurs during the migration of vendor master data, where the system detects that the deletion flag for the same vendor is set differently across different records or systems.
  
  Cause:
  The error arises when:
  
  Multiple vendor records exist for the same vendor across different systems or client environments.
  The deletion flag (LOEVM) is set differently for these records, meaning that one record may be marked for deletion while another is not.
  This inconsistency can lead to issues during data migration, as the system cannot determine a single, consistent state for the vendor.
  
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify the Vendors: Determine which vendors are causing the issue. You can do this by checking the vendor master data in the relevant tables (e.g., LFB1 for vendor master
