• What is the cause and solution for SAP error message CN748 - No authorization to maintain planned independent requirements ?

  The SAP error message CN748 ("No authorization to maintain planned independent requirements") typically occurs when a user attempts to access or modify planned independent requirements (PIR) in the SAP system but lacks the necessary authorizations. This can happen in various modules, particularly in SAP's Production Planning (PP) or Material Management (MM) areas.
  Cause:
  The primary cause of this error is a lack of appropriate authorization in the user's role or profile. The authorization object that is usually associated with this error is C_MRP_PIR, which controls access to planned independent requirements.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after encountering the error. This will show you the last authorization check and help identify which specific authorization is missing.
  Alternatively, you can use transaction code SU01 to view the user's profile and roles.
  
  
  
  Review Authorization Roles:
  
  Check the roles assigned to the user in transaction PFCG. Ensure that the roles include the necessary authorizations for maintaining planned independent requirements.
  If the roles do not have the required authorizations, you may need to modify the role or create a new one that includes the necessary permissions.
  
  
  
  Add Missing Authorizations:
  
  If you have the necessary permissions, you can add the missing authorizations to the user's role. This typically involves adding the C_MRP_PIR authorization object with the appropriate activity (e.g., 01 for create, 02 for change, etc.).
  
  
  
  Consult with Security Team:
  
  If you do not have the necessary access to modify roles or authorizations, contact your SAP security team or administrator. They can assist in reviewing and updating the user's authorizations.
  
  
  
  Testing:
  
  After making changes to the authorizations, have the user log out and log back in to ensure that the new authorizations take effect. Then, attempt to perform the action that previously resulted in the error.
  
  
  
  Related Information:
  
  Authorization Objects: Familiarize yourself with the relevant authorization objects in SAP, particularly those related to MRP and PIR.
  SAP Documentation: Refer to SAP's official documentation or help portal for detailed information on authorization management and troubleshooting authorization issues.
  User Training: Ensure that users are trained on the processes they need to perform and understand the importance of having the correct authorizations.
  
  By following these steps, you should be able to resolve the CN748 error and allow the user to maintain planned independent requirements in SAP.
