• What is the cause and solution for SAP error message /SAPAPO/RES_MSG026 - You are not authorized to display resource network ?

  The SAP error message /SAPAPO/RES_MSG026 indicates that a user does not have the necessary authorization to display a resource network in the SAP Advanced Planning and Optimization (APO) module. This error typically arises when a user attempts to access a resource network without the appropriate permissions.
  Cause:
  The primary cause of this error is a lack of authorization in the user's role or profile. In SAP, access to various functionalities is controlled through authorization objects, and if the user does not have the required authorizations, they will encounter this error message.
  Solution:
  To resolve this issue, you can follow these 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 object is missing.
  
  
  
  Review Authorization Roles:
  
  Check the roles assigned to the user in transaction SU01 (User Maintenance). Ensure that the user has the necessary roles that include access to the APO resource network.
  
  
  
  Modify Roles:
  
  If the user lacks the required authorization, you may need to modify the existing roles or create a new role that includes the necessary authorizations. This can be done using transaction PFCG (Role Maintenance).
  Ensure that the role includes the relevant authorization objects, such as:
  
  S_APO_RES (for resource management)
  S_TCODE (for transaction codes)
  
  
  Make sure to include the necessary activity types (like display, change, etc.) for the resource network.
  
  
  
  Testing:
  
  After making changes to the roles, ask the user to log out and log back in to see if the issue is resolved. They should now be able to access the resource network without encountering the error.
  
  
  
  Consult with Security Team:
  
  If you do not have the necessary permissions to change roles or authorizations, consult with your SAP security team or administrator to assist in granting the required access.
