• What is the cause and solution for SAP error message RSDHA295 - Data type mismatch for mapped procedure input field '&1' ?

  The SAP error message RSDHA295 indicates a data type mismatch for a mapped procedure input field in the context of SAP BW (Business Warehouse) or SAP HANA. This error typically occurs when the data types of the fields in the source system do not match the expected data types in the target system or when there is a mismatch in the data types defined in the InfoObject or transformation.
  Cause:
  
  Data Type Mismatch: The most common cause is that the data type of the source field does not match the data type of the target field in the InfoObject or transformation. For example, if the source field is defined as a string but the target field is defined as an integer, this will lead to a mismatch.
  Incorrect Mapping: The mapping of fields in the transformation might be incorrect, leading to the wrong data type being assigned to a field.
  Changes in Source Structure: If there have been changes in the source system (like changes in the database schema), the data types may have changed, leading to mismatches.
  Inconsistent Data: Sometimes, the data itself may not conform to the expected data type, such as having non-numeric characters in a numeric field.
  
  Solution:
  
  Check Data Types: Verify the data types of the source fields and the target fields in the InfoObject or transformation. Ensure that they match.
  Adjust Mapping: If the mapping is incorrect, adjust it in the transformation to ensure that the correct fields are mapped to the correct data types.
  Data Cleansing: If the data itself is causing the issue, consider implementing data cleansing steps to ensure that the data conforms to the expected formats before loading.
  Update InfoObjects: If there have been changes in the source structure, you may need to update the InfoObjects in BW to reflect these changes.
  Test with Sample Data: Run tests with sample data to ensure that the mappings and data types are correct before executing the full data load.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like RSA1 (Data Warehousing Workbench) to check InfoObjects and transformations.
  Data Source: Check the data source settings in the source system to ensure that the data types are correctly defined.
  Error Logs: Review the error logs in the BW system for more detailed information about the error and the specific fields involved.
  SAP Notes: Look for relevant SAP Notes that may address specific issues related to data type mismatches in your version of SAP BW or HANA.
  
  By following these steps, you should be able to identify and resolve the cause of the RSDHA295 error message.
