• What is the cause and solution for SAP error message WRF_CHAR_VAL075 - You are not authorized to change this characteristic ?

  SAP Error Message:
  
  WRF_CHAR_VAL075 – "You are not authorized to change this characteristic"
  
  Cause:
  This error occurs when a user attempts to change a characteristic value in a classification or variant configuration, but does not have the necessary authorization to perform this action. In SAP, authorizations control who can create, change, or display characteristics and their values. If the user lacks the required authorization object or the correct activity within that object, the system prevents the change and issues this error.
  
  Explanation:
  
  Characteristics are used in classification and variant configuration to define attributes.
  Changing characteristic values is a controlled activity.
  SAP uses authorization objects such as C120 (Classification: Characteristics) to manage access.
  The user’s role/profile must include the authorization to change characteristics (activity 02 = Change).
  
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction SU53 immediately after the error occurs to check which authorization check failed.
  Look for missing authorization objects related to classification, typically C120.
  
  
  
  Verify Authorization Object C120:
  
  Object: C120 (Classification: Characteristics)
  Fields:
  
  ACTVT (Activity): Should include '02' for change.
  KLAH-CLASS (Class type): Relevant class types (e.g., 001 for material).
  KLAH-CLSART (Class type)
  KLAH-CLSART (Class type)
  
  
  Ensure the user has the correct activity (change) for the relevant class type.
  
  
  
  Adjust Roles/Profiles:
  
  If missing, update the user’s role to include the necessary authorization.
  This is done in transaction PFCG by the security/authorization team.
  Add/change the authorization object C120 with activity 02 for the relevant class types.
  
  
  
  Test After Authorization Update:
  
  After updating the roles, have the user log off and log back in.
  Retry the change to the characteristic.
  
  
  
  
  Additional Information:
  
  This error is common in environments with strict authorization controls.
  Sometimes, the user may have display rights but not change rights.
  If the characteristic is part of a variant configuration, similar authorization checks apply.
  For mass changes or transport requests, ensure the user has the appropriate authorizations in the development and production systems.
