• What is the cause and solution for SAP error message RSDHA228 - Target unit of measure cannot be determined ?

  The SAP error message RSDHA228, "Target unit of measure cannot be determined," typically occurs in the context of data extraction or transformation processes, particularly when dealing with data in SAP BW (Business Warehouse) or SAP HANA. This error indicates that the system is unable to determine the appropriate target unit of measure for a particular data field during the data processing or loading phase.
  Causes:
  
  Missing Unit of Measure Mapping: The target unit of measure may not be defined or mapped correctly in the InfoObject or data model.
  Inconsistent Data: The source data may contain inconsistent or missing unit of measure information, leading to difficulties in determining the target unit.
  Configuration Issues: There may be configuration issues in the InfoObjects or data sources that prevent the system from resolving the unit of measure.
  Data Type Mismatch: The data type of the source field may not match the expected data type of the target field, causing the system to fail in determining the unit of measure.
  
  Solutions:
  
  
  Check Unit of Measure Mapping:
  
  Go to the relevant InfoObject and ensure that the unit of measure is correctly defined and mapped.
  Verify that the source and target units of measure are compatible.
  
  
  
  Review Source Data:
  
  Inspect the source data for any missing or inconsistent unit of measure entries.
  Ensure that all records have a valid unit of measure associated with them.
  
  
  
  Configuration Review:
  
  Check the configuration settings in the data model, including InfoObjects, DataSources, and transformation rules.
  Ensure that the transformation rules correctly specify how to handle units of measure.
  
  
  
  Data Type Verification:
  
  Verify that the data types of the source and target fields are compatible.
  If necessary, adjust the data types in the InfoObjects or transformation rules to ensure compatibility.
  
  
  
  Testing and Debugging:
  
  Run a test load or extraction to identify specific records that may be causing the issue.
  Use transaction codes like RSA3 (for DataSource testing) or RSD1 (for InfoObject maintenance) to troubleshoot.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific version of SAP BW or HANA you are using for any known issues or additional guidance.
