• What is the cause and solution for SAP error message VMP_MSG302 - You are not authorized to access Routing information ?

  SAP Error Message:
  
  VMP_MSG302: You are not authorized to access Routing information
  
  Cause:
  This error occurs because the user does not have the necessary authorization to access routing data in SAP. Routing information is typically protected by specific authorization objects, and if the user's role or profile lacks these authorizations, the system will prevent access and display this message.
  
  Explanation:
  
  Routing in SAP refers to the sequence of operations or steps required to manufacture a product.
  Access to routing data is controlled by authorization objects such as:
  
  C_AUFK_AUS (Authorization for routing)
  C_ROUT (Routing authorization)
  
  
  If the user tries to display, change, or create routing information without the required authorization, SAP throws this error.
  
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction SU53 immediately after the error occurs to check which authorization check failed.
  Alternatively, use transaction ST01 (Authorization Trace) to trace the missing authorization.
  
  
  
  Identify Missing Authorization Object:
  
  Typically, the missing authorization object is C_ROUT or related to routing.
  
  
  
  Update User Role:
  
  Contact your SAP Security team.
  Request to add the necessary authorization objects and values to your user role/profile.
  For example, add authorization for object C_ROUT with appropriate activity (e.g., Display, Change).
  
  
  
  Test Access:
  
  After the role update, test accessing routing information again.
  
  
  
  
  Related Information:
  
  Transactions involving routing:
  
  CA01 (Create Routing)
  CA02 (Change Routing)
  CA03 (Display Routing)
  
  
  Authorization Objects:
  
  C_ROUT – Routing authorization
  C_AUFK_AUS – Authorization for routing in production orders
  
  
  SAP Notes:
  
  Check SAP Notes related to authorization issues in routing if the problem persists.
  
  
  Security Best Practices:
  
  Ensure users only get the minimum required authorizations.
  Use role-based access control to manage routing access.
  
  
  
  
  Summary:
  
  
  
  Aspect
  Details
  
  
  
  
  Cause
  Missing authorization to access routing data (e.g., missing C_ROUT object)

  Check Tools
  SU53, ST01 for authorization trace
