• What is the cause and solution for SAP error message INM303 - Navigation not possible; read authorization needed for target object ?

  The SAP error message INM303 ("Navigation not possible; read authorization needed for target object") typically occurs when a user attempts to navigate to a specific object or transaction in SAP but lacks the necessary authorization to access that object. This is a common issue in SAP systems where security and authorization are tightly controlled.
  Cause:
  The primary cause of this error is that the user does not have the required read authorization for the target object they are trying to access. This could be due to:
  
  Missing Authorization Roles: The user may not have been assigned the appropriate roles that grant access to the specific transaction or object.
  Authorization Object Restrictions: The authorization objects associated with the transaction may have restrictions that the user does not meet.
  Profile Issues: The user’s profile may not include the necessary authorizations due to changes in roles or profiles.
  Organizational Level Restrictions: The user may not have access to certain organizational levels (e.g., company codes, plants) that are required to view the object.
  
  Solution:
  To resolve the INM303 error, you can take the following steps:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs. This will show you the last authorization check and help identify which authorization is missing.
  Alternatively, you can use transaction code SU01 to view the user’s roles and authorizations.
  
  
  
  Review Authorization Roles:
  
  Ensure that the user has the necessary roles assigned that include the required authorizations for the target object.
  If roles are missing, work with your SAP security team to assign the appropriate roles.
  
  
  
  Modify Authorization Objects:
  
  If the user has the correct roles but still encounters the error, check the specific authorization objects related to the transaction. You may need to adjust the values or conditions in the authorization objects.
  
  
  
  Consult with Security Team:
  
  If you are not authorized to make changes, contact your SAP security team or administrator. Provide them with the details of the error and the transaction you were trying to access.
  
  
  
  Testing:
  
  After making changes, have the user log out and log back in to ensure that the new authorizations take effect. Test the transaction again to confirm that the issue is resolved.

  Documentation: Review SAP documentation or help resources for more information on authorization management and troubleshooting authorization issues.
