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 'Payment Block'. (This is determined by the
indicator 'Payment Block', field LFA1-SPERZ).
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 Payment Block 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_20900051 - Participating vendors have different Payment Block (LFA1-SPERZ) ?

  The SAP error message CNV_20900051 indicates that there is a discrepancy in the payment block settings for participating vendors in a data migration or conversion process. Specifically, the error arises when the payment block field (LFA1-SPERZ) for different vendors is not consistent, which can lead to issues during the migration of vendor data.
  Cause:
  The error is typically caused by one of the following reasons:
  
  Inconsistent Payment Block Settings: The participating vendors have different values set for the payment block field (LFA1-SPERZ). This inconsistency can occur if the vendors were set up with different payment terms or conditions in the source system.
  Data Migration Issues: During data migration, if the source data contains different payment block settings for vendors that are supposed to be treated as a single entity or group, this error can occur.
  Configuration Differences: There may be differences in the configuration of vendor master data between different systems or environments.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Identify the Vendors: Determine which vendors are causing the issue by checking the error logs or messages that accompany the CNV_20900051 error.
  
  
  Review Payment Block Settings: For the identified vendors, review the payment block settings in the vendor master data (transaction code XK03 or MK03). Check the LFA1-SPERZ field for each vendor.
  
  
  Standardize Payment Block: Decide on a standard payment block setting that should be applied to all participating vendors. Update the vendor master data to ensure that all relevant vendors have the same payment block setting.
  
  
  Data Migration Adjustments: If this error occurs during a data migration process, you may need to adjust the migration mapping or transformation rules to ensure that the payment block settings are consistent across all vendors being migrated.
  
  
  Testing: After making the necessary changes, re-run the migration or conversion process to verify that the error has been resolved.
  
  
  Related Information:
  
  Transaction Codes: Use transaction codes like XK03 (Display Vendor), MK03 (Display Vendor - Purchasing), or SE16N (Data Browser) to check vendor master data.
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or patches related to this error.
  Documentation: Review SAP documentation on vendor master data management and data migration best practices to ensure compliance with standard procedures.
  
  By following these steps, you should be able to resolve the CNV_20900051 error and ensure that your vendor data is consistent and correctly configured for your business processes.
