• What is the cause and solution for SAP error message LTR2_KB_RUNTIME026 - MWB Objects have not been generated yet. ?

  The SAP error message LTR2_KB_RUNTIME026 indicates that the Multi-Provider (MWB) objects have not been generated yet. This typically occurs in the context of SAP BW (Business Warehouse) when you are trying to execute a query or access data that relies on a Multi-Provider that has not been properly set up or activated.
  Cause:
  
  Incomplete Activation: The Multi-Provider or its underlying InfoProviders (like InfoCubes, DataStore Objects, etc.) may not have been activated or generated correctly.
  Missing DataSource: The DataSource that feeds data into the Multi-Provider may not be set up or activated.
  Transport Issues: If the Multi-Provider was transported from another system, it may not have been fully activated in the target system.
  Data Model Changes: Changes made to the underlying InfoProviders after the Multi-Provider was created may require regeneration of the Multi-Provider.
  
  Solution:
  
  
  Activate the Multi-Provider:
  
  Go to the SAP BW modeling tools (transaction RSA1).
  Navigate to the Multi-Provider in the InfoProvider tree.
  Right-click on the Multi-Provider and select "Activate" or "Generate" to ensure it is properly set up.
  
  
  
  Check Underlying InfoProviders:
  
  Ensure that all underlying InfoProviders (InfoCubes, DataStore Objects) are activated and have data loaded.
  If any of the underlying objects are inactive, activate them first.
  
  
  
  Regenerate the Multi-Provider:
  
  If changes were made to the underlying InfoProviders, you may need to regenerate the Multi-Provider.
  Right-click on the Multi-Provider and select "Generate" to regenerate it.
  
  
  
  Check DataSource:
  
  Ensure that the DataSource feeding the Multi-Provider is active and has data available.
  If necessary, refresh the DataSource and load data into the InfoProviders.
  
  
  
  Transport Issues:
  
  If the Multi-Provider was transported, check the transport logs for any errors.
  Ensure that all dependent objects were also transported and activated in the target system.
  
  
  
  Check for Errors in the Process Chain:
  
  If the Multi-Provider is part of a process chain, check the process chain logs for any errors that may have occurred during data loading.
