• What is the cause and solution for SAP error message RSDHA278 - Data type of field '&1' does not match data type of infoObject '&2' ?

  The SAP error message RSDHA278 indicates a data type mismatch between a field in a data source and the corresponding InfoObject in the SAP BW (Business Warehouse) system. This error typically occurs during data loading or when trying to activate a data source or InfoObject.
  Cause:
  
  Data Type Mismatch: The field in the data source (e.g., an ODS, InfoCube, or DataSource) has a different data type than the InfoObject it is mapped to. For example, if the InfoObject is defined as a character type (CHAR) and the field in the data source is defined as a numeric type (NUMC), this error will occur.
  Changes in Data Source: If the structure of the data source has been changed (e.g., a field was added or modified) after the InfoObject was created, it can lead to this mismatch.
  Incorrect Mapping: The mapping between the data source and the InfoObject may not have been set up correctly, leading to mismatched data types.
  
  Solution:
  
  
  Check Data Types: Verify the data types of the field in the data source and the corresponding InfoObject. Ensure that they match. You can do this by:
  
  Going to the DataSource definition and checking the field properties.
  Going to the InfoObject definition and checking the data type.
  
  
  
  Adjust Data Types: If there is a mismatch, you may need to adjust the data type of either the field in the data source or the InfoObject. This may involve:
  
  Modifying the InfoObject to match the data type of the field.
  Changing the data type in the source system if possible.
  
  
  
  Re-map Fields: If the mapping is incorrect, you may need to re-map the fields in the transformation or data flow to ensure that the correct data types are aligned.
  
  
  Activate Objects: After making the necessary changes, ensure that you activate the InfoObject and the DataSource again to reflect the changes.
  
  
  Test Data Load: After resolving the issue, perform a test data load to ensure that the error does not occur again.
  
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like RSA1 (Data Warehousing Workbench) to check InfoObjects and DataSources.
  Documentation: Refer to SAP documentation for detailed information on data types and InfoObject definitions.
  SAP Notes: Check for any relevant SAP Notes that might address specific issues related to this error message.
