  The SAP error message USMD1157 indicates that a user does not have the necessary authorization to perform a specific activity on a particular entity type within a data model. This error typically arises in the context of SAP Master Data Governance (MDG) or similar applications where data models and entities are managed.
  Cause:

  Solution:
  To resolve the USMD1157 error, follow these steps:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs to check the authorization check that failed. This will provide insight into which specific authorization object is missing.

  Review Roles and Profiles:
  
  Ensure that the user has the appropriate roles assigned that include the necessary authorizations for the entity type and activity in question.

  Modify Authorization Objects:
  
  If the existing roles do not cover the required authorizations, you may need to modify the authorization objects associated with those roles. This can involve adding specific entity types and activities to the roles.
  
  
  
  Consult with Security Team:
  
  If you are not authorized to make changes to roles or authorizations, contact your SAP security team or administrator to assist in resolving the authorization issue.
