I'm not sure what or why you are trying to accomplish. Correct me if I'm wrong, but can't you just use a data snapshot? This is used to share data with a team using the team server. Here is a link to the docs: https://docs.mendix.com/howto/data-models/sharing-the-development-database/
For exporting to excel you can use the data grid or the marketplace module, both are explained in this learning path: https://academy.mendix.com/link/modules/136/lectures/1255/7.2.1-Export-to-Excel-Button-on-Data-Grid
For writing data to Teamcenter you need this connector: https://marketplace.mendix.com/link/component/111627
Hope this helps!
