• What is the cause and solution for SAP error message RSES_DS120 - Property 'DeltaInit Simulation' is undefined ?

  The SAP error message RSES_DS120, which states that the property 'DeltaInit Simulation' is undefined, typically occurs in the context of SAP Data Warehousing, particularly when working with DataSources and delta initialization processes in SAP BW (Business Warehouse).
  Cause:
  
  Missing Configuration: The error often arises when the DataSource is not properly configured for delta initialization. This can happen if the delta initialization settings are not defined or if there is a mismatch in the settings.
  Incorrect DataSource Type: The DataSource may not support delta initialization, or it may be incorrectly set up as a non-delta DataSource.
  Transport Issues: If the DataSource was transported from another system, it may not have all the necessary settings or properties defined in the target system.
  Version Compatibility: There may be compatibility issues between the version of SAP BW and the DataSource being used.
  
  Solution:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource in the SAP BW system and check the settings for delta initialization. Ensure that the 'DeltaInit Simulation' property is correctly defined.
  If the DataSource is supposed to support delta, ensure that the delta settings are properly configured.
  
  
  
  Recreate the DataSource:
  
  If the DataSource is not configured correctly, consider recreating it. Make sure to follow the correct steps for setting up a DataSource that supports delta initialization.
  
  
  
  Check for Transport Issues:
  
  If the DataSource was transported, check if all necessary objects and settings were included in the transport request. You may need to manually adjust the settings in the target system.
