  The SAP error message CM_SUB_VALUATION031 indicates that a user does not have the necessary authorization to change a value assignment in a specific valuation assignment type. This error typically arises in the context of materials management, particularly when dealing with classification and valuation of materials.
  Cause:
  The error is caused by a lack of appropriate authorization in the user's role or profile. Specifically, the user is trying to modify a value assignment (like a characteristic value) for a material or object, but their user account does not have the required permissions to perform this action.
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs to see which authorization check failed. This will provide insight into what specific authorization is missing.
  Alternatively, you can use transaction code SU01 to review the user's roles and authorizations.
  
  
  
  Review Role Assignments:
  
  Ensure that the user has the necessary roles assigned that include permissions for changing value assignments. This may involve checking the authorization objects related to material management, such as C_MAT_BW, C_MAT_DTA, or others relevant to your specific configuration.
  
  
  
  Modify Authorizations:
  
  If the user lacks the necessary authorizations, you may need to modify their roles or create a new role that includes the required permissions. This typically requires the involvement of a security administrator or someone with the appropriate access to change user roles.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or your organization's internal guidelines regarding authorization management to ensure compliance with security policies.
  
  
  
  Testing:
  
  After making changes to the user's authorizations, have the user log out and log back in, then attempt the action again to see if the issue is resolved.
