• What is the cause and solution for SAP error message C+258 - Extraction for material &1 failed because of different unit of measures ?

  The SAP error message C+258 indicates that there is a problem with the extraction of data for a material due to a mismatch in the unit of measure (UoM). This typically occurs during the extraction process when the system encounters a situation where the unit of measure for the material being processed does not match the expected unit of measure.
  Cause:
  
  Unit of Measure Mismatch: The most common cause of this error is that the material being extracted has a different unit of measure than what is defined in the extraction logic or the target system.
  Configuration Issues: There may be configuration issues in the material master data or in the extraction settings that lead to this mismatch.
  Data Inconsistencies: Inconsistencies in the data, such as incorrect or missing unit of measure definitions in the material master, can also lead to this error.
  Custom Logic: If there is any custom logic implemented in the extraction process, it may not be handling the unit of measure correctly.
  
  Solution:
  
  Check Material Master Data: Verify the unit of measure settings in the material master (transaction MM03). Ensure that the base unit of measure and any alternative units of measure are correctly defined.
  Review Extraction Logic: If you are using a custom extraction logic or a specific data source, review the logic to ensure that it correctly handles different units of measure.
  Adjust Configuration: If the extraction is part of a specific configuration (like a data source in SAP BW), check the configuration settings to ensure that they align with the units of measure used in the material master.
  Data Consistency Check: Run consistency checks on the data to identify any discrepancies in the unit of measure definitions.
  Consult Documentation: Refer to SAP documentation or notes related to the specific extraction process you are using, as there may be known issues or additional configuration steps required.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like MM03 (Display Material), SE11 (Data Dictionary), and RSA1 (Data Warehousing Workbench) to investigate and resolve the issue.
  SAP Notes: Check for relevant SAP Notes that may address this specific error or provide guidance on handling unit of measure issues in data extraction.
  Support: If the issue persists after checking the above points, consider reaching out to SAP support or your internal SAP team for further assistance.
  
  By following these steps, you should be able to identify and resolve the cause of the C+258 error in SAP.
