• What is the cause and solution for SAP error message /PLMI/RTG_RUC004 - Routing &1 already loaded ?

  The SAP error message /PLMI/RTG_RUC004 Routing &1 already loaded typically indicates that there is an attempt to load a routing that has already been loaded into the system. This can occur in various scenarios, such as during the execution of a program or transaction that processes routings.
  Cause:
  
  Duplicate Load Attempt: The routing identified by &1 is already present in the system, and the system does not allow loading the same routing multiple times.
  Session Management: If multiple sessions or processes are trying to load the same routing simultaneously, it can lead to this error.
  Data Integrity Checks: The system may have built-in checks to prevent duplicate entries for data integrity purposes.
  
  Solution:
  
  Check Existing Routings: Verify if the routing &1 is already loaded in the system. You can do this by navigating to the relevant transaction (e.g., CA03 for displaying routings) and checking if the routing exists.
  Avoid Duplicate Loads: Ensure that your process or program logic does not attempt to load the same routing multiple times. Implement checks in your code to prevent this.
  Session Management: If you are running multiple sessions, ensure that they are not trying to load the same routing simultaneously. You may need to serialize the load requests.
  Error Handling: Implement error handling in your program to gracefully manage situations where a routing is already loaded, possibly by skipping the load or logging a message.
  Consult Documentation: Review SAP documentation or notes related to the specific module you are working with, as there may be additional context or updates regarding this error.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CA03 (Display Routing), CA02 (Change Routing), and CA01 (Create Routing) to manage routings effectively.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. You can search the SAP Support Portal for specific notes that may address this issue.
  Debugging: If you have access to debugging tools, you can trace the execution of the program to identify where the duplicate load attempt is occurring.
