• What is the cause and solution for SAP error message RSAOLTP010 - The data type of InfoObject &1 is incompatible with field &2 ?

  The SAP error message RSAOLTP010 indicates that there is a data type mismatch between an InfoObject and a field in a data source or a transformation. This typically occurs in the context of SAP BW (Business Warehouse) when you are trying to load data from a source system into an InfoProvider, and the data types of the fields do not match.
  Cause:
  
  Data Type Mismatch: The InfoObject (e.g., a characteristic or key figure) has a different data type than the corresponding field in the source system or the data source.
  Field Length Issues: The length of the field in the source system may exceed the length defined for the InfoObject.
  Incompatible Data Types: For example, trying to load a numeric value into a character field or vice versa.
  Changes in Source Structure: If the source system structure has changed (e.g., a field was added or modified), it may lead to this error.
  
  Solution:
  
  
  Check Data Types: Verify the data types of the InfoObject and the corresponding field in the source system. Ensure they are compatible.
  
  You can do this by checking the InfoObject definition in the SAP BW system and comparing it with the data source structure.
  
  
  
  Adjust InfoObject Definition: If necessary, modify the InfoObject to match the data type and length of the source field.
  
  This can be done in the SAP BW modeling tools (e.g., RSA1 transaction).
  
  
  
  Modify Data Source: If the InfoObject cannot be changed, consider modifying the data source or transformation to ensure that the data types match.
  
  You may need to use a transformation to convert data types or lengths appropriately.
  
  
  
  Check Transformation Rules: Review the transformation rules to ensure that they are correctly mapping the fields and that any necessary conversions are applied.
  
  
  Test Data Load: After making the necessary adjustments, test the data load again to ensure that the error is resolved.
  
  
  Related Information:
  
  Transaction Codes: Use transaction codes like RSA1 (Data Warehousing Workbench) to access InfoObjects and transformations.
  Data Source: Check the data source definition in the source system to understand the structure and data types.
  SAP Notes: Look for relevant SAP Notes that may address specific issues related to this error message.
  Documentation: Refer to SAP BW documentation for best practices on data modeling and transformations.
  
  By following these steps, you should be able to identify and resolve the RSAOLTP010 error effectively.
