• What is the cause and solution for SAP error message RJ108 - InfoSource exists already ?

  The SAP error message RJ108, which states "InfoSource exists already," typically occurs in the context of SAP BW (Business Warehouse) when you are trying to create or activate an InfoSource that already exists in the system. An InfoSource is a data structure that is used to transfer data from a source system to a target system in SAP BW.
  Cause:
  The error is triggered when:
  
  You attempt to create a new InfoSource with the same name as an existing one.
  There may be a naming conflict due to a previous configuration or an incomplete deletion of an InfoSource.
  The InfoSource might be in use or referenced by other objects, preventing its recreation.
  
  Solution:
  To resolve the RJ108 error, you can follow these steps:
  
  
  Check Existing InfoSources:
  
  Go to the SAP BW modeling tools and check the list of existing InfoSources to confirm if the one you are trying to create already exists.
  Use transaction code RSA1 to access the Data Warehousing Workbench and navigate to the InfoSources section.
  
  
  
  Rename or Modify:
  
  If the InfoSource already exists and you need to create a new one, consider renaming your new InfoSource to avoid the conflict.
  Alternatively, if the existing InfoSource is no longer needed, you can delete it (ensure that it is not in use).
  
  
  
  Check Dependencies:
  
  If the existing InfoSource is in use, check for any dependencies or objects that reference it. You may need to adjust these references before making changes.
  
  
  
  Transport Requests:
  
  If you are working in a development environment and plan to transport changes to a production environment, ensure that the InfoSource is included in the transport request correctly.
  
  
  
  Activation:
