Open a Data Object in the following ways:

Step I: Open the Data Object User Interface.

Option I: On the Home page, click Data Objects tile header.

Option II: On the Navigation pane, click Data Object.

The canvas displays a list of all the available Data Objects.

Step II: Open a Data Object by clicking on the Data Object name. 

Alternatively, to open single or multiple Data Objects together, select the Data Objects on canvas, and on the Actions menu, click More. Then, under More actions, click Open.

The Data Object selected first opens in the canvas area.

The Opened Objects pane displays the list of all opened objects. Click on specific Data Object, to open it in the canvas.

Once a Data Object is open, it gets locked for edit and it opens in read-only mode for other users.
