• What is the cause and solution for SAP error message RSM406 - Source InfoObject & is in the update, but not in the comm. structure ?

  The SAP error message RSM406 indicates that there is a discrepancy between the InfoObject and the communication structure in the context of data extraction or data loading processes, particularly in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence).
  Cause:
  The error occurs when an InfoObject (a characteristic or key figure) is included in the update process but is not present in the communication structure (the data structure used for data transfer). This can happen due to several reasons:
  
  Changes in InfoObjects: If an InfoObject was recently added or modified and the communication structure was not updated accordingly.
  Inconsistent Data Model: The data model may have inconsistencies where the InfoObject is expected in the update but is missing from the communication structure.
  Transport Issues: If changes were transported from one system to another (e.g., from development to production) and the communication structure was not included in the transport request.
  
  Solution:
  To resolve the RSM406 error, you can follow these steps:
  
  
  Check the Communication Structure:
  
  Go to the relevant DataSource in the SAP BW system.
  Verify that the InfoObject in question is included in the communication structure. You can do this by navigating to the DataSource and checking the fields defined in the communication structure.
  
  
  
  Update the Communication Structure:
  
  If the InfoObject is missing, you need to add it to the communication structure. This can be done in the DataSource maintenance transaction (e.g., RSA1).
  After adding the InfoObject, make sure to activate the DataSource.
  
  
  
  Recheck the DataSource:
  
  After making changes, recheck the DataSource to ensure that it is correctly configured and that all required InfoObjects are included.
  
  
  
  Transport Changes:
  
  If the issue arose after a transport, ensure that the communication structure was included in the transport request. If not, you may need to create a new transport request that includes the necessary changes.
  
  
  
  Test the Data Load:
  
  After making the necessary adjustments, test the data load again to ensure that the error is resolved.
  
  
  
  Related Information:

  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to this error message.
