How To Fix CNV_20900181 - Participating vendors have different Deletion flag (LFA1-LOEVM)

CNV_20900181 - Overview

• Message type: E = Error

• Message class: CNV_20900 - Message class for package CNV_20900

• Message number: 181

• Message text: Participating vendors have different Deletion flag (LFA1-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 Central Deletion Flag for Master Record.(This is
determined by the indicator 'Central Deletion Flag for Master Record',
field <ZH>LFA1-LOEVM</>).
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 Central Deletion Flag for Master Record of the old vendor
record number 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.

CNV_20900181 - Details

• The SAP error message CNV_20900181 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 a data migration project, such as when using the SAP S/4HANA Migration Cockpit or other data transfer tools.
  
  Cause:
  The error arises when there are multiple vendor records (in the LFA1 table) that are being processed, and these records have different values for the deletion flag (LOEVM). The deletion flag indicates whether a vendor is marked for deletion. If one vendor is marked for deletion and another is not, the system cannot proceed with the operation because it expects consistency in the deletion status across the participating vendors.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Vendors: Determine which vendors are causing the issue. You can do this by querying the LFA1 table for the vendors involved in the migration
