• What is the cause and solution for SAP error message RSDS091 - &1: Data type &2 deviates from domain (&3) ?

  The SAP error message RSDS091 indicates that there is a mismatch between the data type of a field in your data source and the expected data type defined in the domain. This typically occurs in the context of SAP BW (Business Warehouse) when you are trying to load data into an InfoObject or when you are working with data sources.
  Cause:
  The error message RSDS091 occurs due to one of the following reasons:
  
  Data Type Mismatch: The data type of the field in the source system does not match the data type defined in the target InfoObject or data target in SAP BW.
  Domain Definition: The domain associated with the InfoObject has specific data type constraints that are not being met by the incoming data.
  Transformation Rules: If you are using transformations to map fields from the source to the target, there may be an incorrect mapping or conversion that leads to this error.
  
  Solution:
  To resolve the RSDS091 error, you can follow these steps:
  
  
  Check Data Types:
  
  Verify the data type of the field in the source system. You can do this by checking the data source or the underlying table in the source system.
  Compare it with the data type defined in the InfoObject or target data structure in SAP BW.
  
  
  
  Adjust Domain Settings:
  
  If the data type in the source is correct but does not match the domain, you may need to adjust the domain settings in SAP BW. This could involve changing the data type of the InfoObject or modifying the domain to accept the incoming data type.
  
  
  
  Modify Transformation:
  
  If you are using a transformation, check the mapping rules. Ensure that the source field is correctly mapped to the target field and that any necessary conversions are applied.
  
  
  
  Data Cleansing:
  
  If the incoming data contains invalid values that do not conform to the expected data type (e.g., alphanumeric characters in a numeric field), you may need to cleanse the data before loading it into SAP BW.
  
  
  
  Testing:
  
  After making the necessary adjustments, perform a test load to ensure that the error is resolved.
  
  
  
  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.
  Documentation: Refer to SAP documentation for detailed information on data types, domains, and InfoObjects.
  
  By following these steps, you should be able to identify and resolve the cause of the RSDS091 error in your SAP BW environment.
