• What is the cause and solution for SAP error message RSDS089 - &1: Data type &2 deviates from data element (&3) ?

  The SAP error message RSDS089 indicates a data type mismatch in the context of DataSources, typically when working with SAP BW (Business Warehouse) or SAP BI (Business Intelligence). This error occurs when the data type of a field in the DataSource does not match the expected data type defined in the data element.
  Cause:
  The error message RSDS089 is triggered when:
  
  The data type of a field in the DataSource (e.g., a field in an InfoSource or DataSource) does not match the data type defined in the corresponding data element.
  This can happen due to changes in the underlying data structure, such as changes in the source system or modifications made to the DataSource itself.
  
  Solution:
  To resolve the RSDS089 error, you can follow these steps:
  
  
  Check DataSource Definition:
  
  Go to the DataSource in the SAP BW system and check the field definitions.
  Compare the data types of the fields in the DataSource with the data types defined in the corresponding data elements.
  
  
  
  Adjust Data Types:
  
  If you find a mismatch, you may need to adjust the data type in the DataSource to match the data element.
  This can involve modifying the DataSource or the underlying structure in the source system.
  
  
  
  Re-activate DataSource:
  
  After making changes, you may need to re-activate the DataSource to ensure that the changes take effect.
  You can do this by going to the DataSource in the Data Warehousing Workbench and selecting the option to activate it.
  
  
  
  Check for Source System Changes:
  
  If the source system has undergone changes (e.g., changes in the database schema), ensure that the DataSource is updated accordingly to reflect these changes.
  
  
  
  Test the DataSource:
  
  After making the necessary adjustments, test the DataSource to ensure that it is functioning correctly and that the error no longer appears.
