Changing the Column setting for the card number (stage 3)
Carry out this stage only if your Quantum file contains card numbers. This is because Metadata Model to Quantum does not allow you to specify the starting column of the card number.
1 In Metadata Model Explorer, click File > Open Document.
2 Select the .mdd file that you saved in the previous step, and then click Open.
3 Click Custom Properties (Datasource), and then double-click CardNum_ColStart.
4 Change the number in the top text box to the starting column of the card number on your Quantum file, and then click OK.
5 Click Tools > Save As to save the .mdd file, and then close Metadata Model Explorer.
You can now use the questionnaire definition (.mdd) file to read your Quantum file.
