To test your mappings:

• Click the Message Browser button on the toolbar, and paste the test message into the Message Browser.
• Click the Table View tab, and choose the Grammar View option.
• Click the Parse button. The data that will be extracted into the sub-table you created is displayed in the right pane.

Message Browser, Showing Extracted Data

You will notice that each repeating Attending Doctor field is in a separate row, but within the same DoctorSubTable.

	Note that the right pane displays the data much like a table in a database, but instead displays columns on the left side and the row number along the top. This view is useful for verifying that your mappings are not only correct, but to also check what data will be mapped from incoming messages. If the parse is successful, your tables will be correctly populated. If the parse fails, an error message will be displayed, similar to the one that would appear at runtime.
