SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20900 - Message class for package CNV_20900

• Message number: 062

• Message text: Participating vendors have different Bank keys (LFBK-BANKL)

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 'Bank Keys'. (This is determined by the indicator
'Bank Keys', field LFBK-BANKL).
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 Bank Keys 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.

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

• What is the cause and solution for SAP error message CNV_20900062 - Participating vendors have different Bank keys (LFBK-BANKL) ?

  The SAP error message CNV_20900062 indicates that there is a discrepancy in the bank keys (bank account identifiers) for participating vendors during a data migration or conversion process. This error typically arises in scenarios where multiple vendors are being processed, and the system detects that the bank keys associated with these vendors do not match.
  Cause:
  The primary cause of this error is that the participating vendors have different bank keys (LFBK-BANKL) in the vendor master data. This can happen due to:
  
  Data Inconsistency: The vendor records may have been created or maintained inconsistently, leading to different bank keys for what should be the same vendor or related vendors.
  Data Migration Issues: During data migration from legacy systems to SAP, if the bank details were not mapped correctly, it could lead to this error.
  Vendor Duplication: There may be duplicate vendor entries with different bank keys, which can cause conflicts during processing.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Vendor Master Data:
  
  Review the vendor master records in SAP (transaction code XK03 or MK03) to identify the bank keys associated with the vendors in question.
  Ensure that the bank keys are consistent across the relevant vendor records.
  
  
  
  Data Cleansing:
  
  If discrepancies are found, you may need to clean up the vendor master data. This could involve merging duplicate vendors or updating bank details to ensure consistency.
  
  
  
  Update Bank Keys:
  
  If necessary, update the bank keys for the vendors to ensure they match. This can be done using transaction codes like XK02 or MK02 for changing vendor data.
  
  
  
  Review Migration Mapping:
  
  If this error occurred during a data migration process, review the mapping of bank details from the legacy system to ensure that they are correctly aligned with the SAP structure.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific migration or conversion process you are using, as there may be specific guidelines or tools provided by SAP to handle such issues.
  
  
  
  Testing:
  
  After making the necessary changes, re-run the migration or conversion process to check if the error persists.
