• What is the cause and solution for SAP error message R1120 - Transaction code &1 assigned to multiple application transactions ?

  The SAP error message R1120 indicates that a transaction code (T-code) is assigned to multiple application transactions. This typically occurs when there is a conflict in the assignment of T-codes to different applications or functions within the SAP system.
  Cause:
  
  Duplicate Assignment: The T-code has been assigned to more than one application transaction, which is not allowed in SAP.
  Configuration Error: There may be a configuration error in the transaction code assignment in the SAP system.
  Custom Development: If custom transactions have been developed, they may inadvertently use the same T-code as standard transactions.
  
  Solution:
  
  
  Identify Conflicting Assignments:
  
  Use transaction code SE93 to check the assignment of the T-code in question. This will show you which application transactions are currently assigned to the T-code.
  
  
  
  Review and Modify Assignments:
  
  Determine which application transaction should retain the T-code and which one should be changed.
  If necessary, reassign the T-code to a different application transaction or create a new T-code for one of the conflicting transactions.
  
  
  
  Check Custom Developments:
  
  If the issue arises from custom developments, review the custom code to ensure that it does not conflict with standard SAP transactions.
  
  
  
  Transport Changes:
  
  If changes are made in a development environment, ensure that they are transported to the production environment properly.
  
  
  
  Testing:
  
  After making changes, test the transactions to ensure that they work as expected without conflicts.
  
  
  
  Related Information:
  
  Transaction Codes: Transaction codes are unique identifiers for specific functions or applications within SAP. Each T-code should be unique to avoid conflicts.
  Authorization Issues: Sometimes, authorization issues can also lead to confusion regarding transaction assignments. Ensure that users have the correct authorizations for the transactions they are trying to access.
  Documentation: Keep documentation of any changes made to T-code assignments for future reference and to assist in troubleshooting.
  
  If the problem persists after following these steps, it may be beneficial to consult with your SAP Basis or security team for further assistance.
