• What is the cause and solution for SAP error message RTC_FLUP_01021 - Upload data incorrect; key field '&1' value '&2' must be '&3' ?

  The SAP error message RTC_FLUP_01021 indicates that there is an issue with the data being uploaded, specifically related to a key field. The message format suggests that the key field identified by &1 has a value of &2, but it should actually be &3. This typically occurs during data uploads in SAP, such as when using the LSMW (Legacy System Migration Workbench), BAPIs, or other data upload tools.
  Cause:
  
  
  Incorrect Data: The value being uploaded for the specified key field does not match the expected value in the target system. This could be due to:
  
  Typographical errors in the data being uploaded.
  Incorrect mapping of fields in the upload template.
  Data that does not exist in the target system (e.g., trying to reference a non-existent record).
  
  
  
  Data Integrity Issues: The data being uploaded may violate referential integrity constraints. For example, if the key field is supposed to reference another table or entity, and the corresponding record does not exist, this error will occur.
  
  
  Configuration Issues: There may be configuration settings in the target system that expect a certain format or value for the key field.
  
  
  Solution:
  
  
  Verify Data: Check the data being uploaded for the specified key field. Ensure that the value matches what is expected in the target system. Look for:
  
  Typos or formatting issues.
  Correctness of the data in the source system.
  
  
  
  Check Mapping: If you are using a data upload tool, verify that the mapping of fields is correct. Ensure that the key field in your upload template corresponds to the correct field in the target system.
  
  
  Data Existence: Ensure that the value you are trying to upload exists in the target system. If it is supposed to reference another record, make sure that record is created before the upload.
  
  
  Consult Documentation: Review any relevant documentation or guidelines for the data upload process to ensure compliance with expected formats and values.
  
  
  Test with Sample Data: If possible, try uploading a small set of data that you know is correct to see if the error persists. This can help isolate the issue.
  
  
  Error Logs: Check the error logs or detailed messages provided by SAP during the upload process for additional context on the error.
