• What is the cause and solution for SAP error message RSO420 - &1 &2 cannot be deleted because of references ?

  The SAP error message RSO420 indicates that a specific object (like a query, InfoObject, or other BI-related object) cannot be deleted because it has existing references. This is a common issue in SAP BW (Business Warehouse) and can occur in various contexts, such as when trying to delete a query, InfoObject, or other related objects.
  Cause:
  The error occurs because the object you are trying to delete is still being referenced by other objects or processes in the system. This could include:
  
  Queries that are based on the InfoObject.
  Data sources that are linked to the InfoObject.
  Other InfoObjects that depend on the object you are trying to delete.
  Active or scheduled processes that utilize the object.
  
  Solution:
  To resolve the RSO420 error, you need to identify and remove the references to the object you are trying to delete. Here are the steps you can take:
  
  
  Identify References:
  
  Use transaction codes like RSO1 (for InfoObjects) or RSRT (for queries) to check where the object is being used.
  You can also use the RSOBJV transaction to find dependencies and references for the object.
  
  
  
  Remove Dependencies:
  
  If the object is being used in queries, you will need to delete or modify those queries first.
  If it is being used in data sources or other InfoObjects, you will need to address those dependencies as well.
  
  
  
  Check for Active Processes:
  
  Ensure that there are no active or scheduled processes that are using the object. You can check the process chains and other scheduled jobs.
  
  
  
  Delete the Object:
  
  Once all references have been removed, you should be able to delete the object without encountering the RSO420 error.
  
  
  
  Use the Object List:
  
  In some cases, you can use the object list in the Data Warehousing Workbench to see all objects and their dependencies.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSO1, RSRT, RSOBJV, and RSA1 for managing InfoObjects and queries.
  Documentation: Refer to SAP Help documentation for more detailed information on managing objects in SAP BW.
  System Logs: Check system logs for additional error messages or warnings that might provide more context on the issue.
  
  By following these steps, you should be able to resolve the RSO420 error and successfully delete the object in question.
