Smart SAP Assistant

• What is the cause and solution for SAP error message WSTI_CALC004 - No authorization for executing this function in plant &1 ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WSTI_CALC004 No authorization for executing this function in plant &1
  
  Cause:
  This error occurs because the user attempting to execute a specific function related to work scheduling, production planning, or capacity planning does not have the necessary authorization for the specified plant (&1).
  In SAP, authorizations are controlled via roles and profiles assigned to users. Each plant is a key organizational unit, and certain functions require explicit authorization for that plant. If the user lacks the required authorization object values (e.g., for plant or work center), the system prevents execution and throws this error.
  
  Typical Scenarios:
  
  User tries to run capacity planning or scheduling transactions (e.g., CM01, CM21, MF50, or similar).
  User attempts to execute functions related to work center or plant-specific operations.
  Authorization objects related to plant (e.g., B_PLANT, C_APPL, C_AUTH, C_TCODE) are missing or incomplete in the user's role.
  
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction SU53 immediately after the error occurs to display the last failed authorization check.
  Identify which authorization object and field values are missing.
  
  
  
  Review and Update Roles:
  
  Use transaction PFCG to check the roles assigned to the user.
  Verify that the roles include the necessary authorization objects with the correct plant (&1) values.
  Common authorization objects to check:
  
  B_PLANT (Plant)
  C_APPL (Application)
  C_AUTH (Authorization for capacity planning)
  C_TCODE (Transaction code authorization)
  
  
  
  
  
  Assign or Adjust Authorizations:
  
  Add or adjust the plant authorization in the user's role.
  If the user needs access to multiple plants, ensure all relevant plants are included.
  After changes, regenerate and assign the role to the user.
  
  
  
  Test the Function:
  
  Have the user retry the function after authorization updates.
  Confirm that the error no longer appears.
  
  
  
  
  Additional Information:
  
  This error is common in environments with strict plant-level authorization controls.
  Always follow your organization's security policies when granting authorizations.
  If unsure about which authorizations are needed, consult with your SAP security team or BASIS administrator.
  Sometimes, the error can also occur if the plant is not maintained correctly in master data or if the user is trying to access a plant that does not exist or is inactive.
