• What is the cause and solution for SAP error message CNV_20900001 - Format error: Vendor &1 has more than &2 characters ?

  The SAP error message CNV_20900001 indicates that there is a format error related to a vendor's name or identifier. Specifically, it means that the vendor identified by &1 has a name or identifier that exceeds the maximum allowed length of &2 characters.
  Cause:
  This error typically arises during data migration or data upload processes, particularly when using SAP's data migration tools or during the execution of a conversion program. The root causes can include:
  
  Data Length Exceedance: The vendor name or identifier in the source data exceeds the length defined in the target SAP system.
  Incorrect Mapping: The mapping of fields from the source system to the target system may not align correctly, leading to longer values being placed in fields with shorter length restrictions.
  Data Quality Issues: The source data may contain unexpected or malformed entries that do not conform to the expected format.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  Identify the Vendor: Check the specific vendor mentioned in the error message (&1) to understand its current name or identifier.
  Check Field Lengths: Review the target field definitions in the SAP system to confirm the maximum allowed length for vendor names or identifiers. This can typically be found in the data dictionary (transaction SE11).
  Data Cleansing: If the vendor name exceeds the allowed length, you may need to:
  
  Shorten the vendor name in the source data to fit within the allowed character limit.
  Consider using abbreviations or alternative naming conventions that comply with the length restrictions.
  
  
  Adjust Mapping: If the error is due to incorrect mapping, ensure that the data mapping configuration is set up correctly to match the lengths and formats expected by the target system.
  Re-run the Migration: After making the necessary adjustments, re-run the data migration or upload process to see if the error is resolved.
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like SE11 (Data Dictionary), SE16 (Data Browser), or ST22 (Dump Analysis) to investigate further.
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or patches related to this error.
  Data Migration Tools: If you are using tools like SAP S/4HANA Migration Cockpit or LSMW (Legacy System Migration Workbench), refer to their documentation for specific guidelines on handling data length issues.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
