• What is the cause and solution for SAP error message DBOSC571 - Selecting more than two different units is not allowed ?

  The SAP error message DBOSC571 ("Selecting more than two different units is not allowed") typically occurs in the context of database operations or when working with certain reports or transactions that involve unit conversions or measurements. This error indicates that the system has detected an attempt to select or process more than two different units of measure in a single operation, which is not permitted.
  Cause:
  
  Multiple Units of Measure: The error is triggered when a user tries to select or process data that involves more than two different units of measure. For example, if you are trying to analyze or report on quantities that are expressed in different units (e.g., kilograms, pounds, liters), the system restricts this to avoid confusion and ensure data integrity.

  Data Entry Errors: Users may inadvertently select multiple units when entering data or generating reports.
  
  Solution:
  
  Limit Unit Selection: When performing the operation that triggers the error, ensure that you are only selecting up to two different units of measure. Review your selection criteria and adjust them accordingly.
  Check Configuration: If you believe the error is due to system configuration, consult with your SAP administrator or technical team to review the settings related to units of measure. They may need to adjust the configuration to allow for more flexibility if appropriate.
  Data Validation: Ensure that the data being processed does not inadvertently include multiple units. Validate the data entries to confirm that they conform to the expected units of measure.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on the transaction or report you are using. There may be additional constraints or recommendations provided by SAP.
