To create a sub-table to hold the extracted data:

• Under Segments, double-click PV1 (Patient Visit). The PV1 Segment window appears.
• Navigate to the Attending Doctor field (7), and verify the Data Type is XCN.
• Under Composites, double-click the XCN composite. The XCN Composite window appears.

The next step is to create a table, called DoctorSubTable, with six columns identical to the first six fields in the XCN composite.

• Create a new table by clicking the Table icon in the toolbar.
• Right-click Table0 in the Workspace, and select Rename Table0. The Enter New Name window appears.
• Rename this table, DoctorSubTable, and click OK.

The next step is to add a table group to the Table Grammar.
