How To Fix CNV_20900053 - Participating vendors have different Central deletion block (LFA1-NODEL)

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20900 - Message class for package CNV_20900

• Message number: 053

• Message text: Participating vendors have different Central deletion block (LFA1-NODEL)

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 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 block for master record'. (This
is determined by the indicator 'Central deletion block for master
record', field LFA1-NODEL).
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.

How to fix this error?

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 block for master record of the old vendor
record for which priority the 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_20900053 - Participating vendors have different Central deletion block (LFA1-NODEL) ?

  The SAP error message CNV_20900053 indicates that there is a discrepancy in the Central deletion block (field NODEL in table LFA1) among participating vendors during a data migration or conversion process. This typically occurs in scenarios where vendor data is being consolidated or migrated, and the system detects that the vendors involved have different settings for the deletion block.
  Cause:
  The error arises when:
  
  Multiple vendor records are being processed, and at least one of them has a different value in the NODEL field.
  The NODEL field indicates whether a vendor is blocked for deletion. If one vendor is marked as blocked for deletion and another is not, the system will raise this error to prevent inconsistencies.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Vendor Records:
  
  Use transaction code SE16N or SE11 to view the LFA1 table.
  Check the NODEL field for the vendor records involved in the migration. Identify which vendors have different values.
  
  
  
  Standardize the Deletion Block:
  
  Decide on a consistent approach for the NODEL field. You may want to:
  
  Set all participating vendors to the same value (either all blocked or all unblocked).
  Update the vendor records accordingly using transaction XK02 (Change Vendor) or through a mass update if necessary.
  
  
  
  
  
  Re-run the Migration:
  
  After ensuring that all participating vendors have the same NODEL value, re-run the migration or conversion process.
  
  
  
  Consult Documentation:
  
  If you are using a specific migration tool (like SAP S/4HANA Migration Cockpit), refer to the relevant documentation for any additional steps or considerations.
  
  
  
  Testing:
  
  After making changes, perform a test run of the migration to ensure that the error does not reoccur.
  
  
  
  Related Information:
  
  Field NODEL: This field in the LFA1 table indicates whether a vendor is blocked for deletion. A value of 'X' means the vendor is blocked, while a blank value means it is not blocked.
  Data Migration Tools: If you are using SAP's data migration tools, ensure that you are following the best practices for data consistency and integrity.
  SAP Notes: Check for any relevant SAP Notes that might provide additional insights or solutions related to this error message.
  
  By following these steps, you should be able to resolve the CNV_20900053 error and proceed with your data migration or conversion process.
