How To Fix RJ042 - DataSource &1 is extracted using functional module &2

SAP Error Message - Details

• Message type: E = Error

• Message class: RJ - BW Extractor Handling Message Class

• Message number: 042

• Message text: DataSource &1 is extracted using functional module &2

What causes this issue?

Data from DataSource &v1& has been extracted using function module &v2&.
If you edit and save the DataSource by maintaining generic extraction,
extraction no longer takes place using this function module, but is
performed by a database view, a transparent table, a functional area of
SAP query, or a self-defined extraction module.
If &v1& is included in the deliverd SAP Content, you can activate
extraction using function module &v2& again by transferring this Content
with transaction RSA5 or the IMG.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message RJ042 - DataSource &1 is extracted using functional module &2 ?

  The SAP error message RJ042 indicates that a DataSource is being extracted using a specific functional module, which may not be the intended or correct method for extraction. This error typically arises in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when there are issues with the extraction process from a source system.
  Cause:
  
  Incorrect Configuration: The DataSource may not be properly configured to use the specified functional module for extraction.
  Functional Module Issues: The functional module itself may have issues, such as being inactive, not properly implemented, or not suitable for the DataSource.
  DataSource Type: The DataSource might be of a type that does not support extraction via the specified functional module.
  Authorization Issues: There may be authorization problems preventing the extraction from occurring correctly.
  
  Solution:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource in the SAP BW system and verify its configuration. Ensure that it is set up to use the correct functional module.
  If necessary, reconfigure the DataSource to point to the correct functional module.
  
  
  
  Review Functional Module:
  
  Check the functional module specified in the error message. Ensure that it is active and correctly implemented.
  Test the functional module independently to ensure it is functioning as expected.
  
  
  
  DataSource Type Verification:
  
  Confirm that the DataSource type is compatible with the extraction method being used. If it is not, consider using a different extraction method or DataSource.
  
  
  
  Authorization Check:
  
  Ensure that the user executing the extraction has the necessary authorizations to access the DataSource and the functional module.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific DataSource and functional module for any known issues or additional configuration steps.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the extraction process to identify any underlying problems.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific DataSource or functional module.
  Transaction Codes: Use transaction codes like RSA1 (Data Warehousing Workbench) to manage DataSources and monitor extraction processes.
  Logs: Review logs in the SAP system for additional error messages or warnings that may provide more context about the issue.
  
  If the problem continues after following these steps, it may be beneficial to reach out to SAP support or consult with a technical expert familiar with SAP BW/BI extraction processes.
