Specifically, it means that a column has been added or modified in the table referenced by the DataSource.
  Cause:
  This error typically occurs when:
  
  A table in the source system (like a database) has been altered (e.g., a new column has been added or an existing column has been modified).
  The DataSource in SAP BW or Data Services is not updated to reflect these changes.
  The DataSource is trying to read data from a table that has a different structure than what is defined in the DataSource.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the Source Table: Verify the structure of the source table in the database to confirm what changes have been made (e.g., new columns added, existing columns modified).
  
  
  Update the DataSource:
  
  Go to the DataSource in SAP BW or Data Services.
  Refresh or re-import the DataSource to reflect the changes made in the source table.
  If you are using SAP BW, you can do this by navigating to the DataSource in the Data Warehousing Workbench and using the "Change" option to update the structure.
  
  
  
  Adjust Transformations: If the DataSource is used in any transformations or queries, ensure that these are updated to accommodate the new or modified columns.
  
  
  Activate the DataSource: After making the necessary changes, activate the DataSource to ensure that it is ready for data extraction.
  
  
  Test the Data Extraction: Perform a test extraction to ensure that the DataSource is functioning correctly and that the error is resolved.
  
  
  Related Information:
  
  DataSource: A DataSource in SAP BW is a structure that defines how data is extracted from a source system. It can be based on database tables, views, or other data sources.

  SAP Notes: Check for any relevant SAP Notes that might provide additional guidance or solutions related to this error message.
