Unable to Save Changes to Model via Tabular Editor

Hi VenuBollineni 
Thank you for reaching out to the Microsoft community forum. I understand that you are experiencing an issue with saving changes to the model via Tabular Editor using the XMLA endpoint.

• Please verify the existence of the database with the specified ID on the server by reviewing the server's database list.
  
• Please verify that your user account holds either the Admin or Contributor role within the workspace. If your access is limited to Viewer or Member, you will not be able to make changes through the XMLA endpoint

Please try the above steps and provide us with the required information, such as the semantic model mentioned earlier by vanessafvg .

Thank you
