AccurioPro will prompt you to select a data file the first time AccurioPro wishes to apply one to a document's DDF. Additionally, if a data file has already been selected for a document's DDF, then by default AccurioPro will display a Verify Data File dialog each time the document's DDF will be using that data file. An example is shown below:

This dialog allows you to immediately identify the name of the data file that AccurioPro is about to process and provides several choices:

Select Data File: Click this button to choose a different data file for this merge session.

Cancel: Click this button to cancel the merge session.

Use Current Data File: Click this button to confirm the data file selection and continue with this merge session. 

Prompt for Data File Each Time: This preference determines whether AccurioPro VDPmpts you to confirm which data file to use when processing data for any document.

• Select this check box if you would like AccurioPro to continue to display the Verify Data File dialog before processing data for a document.
• Deselect this check box if you prefer AccurioPro no longer prompt you to confirm which data file to use on a document. When this preference is deselected, AccurioPro will automatically use the data file that was previously selected for the current document's DDF without prompting you for confirmation.

You can change your Prompt for Data File Each Time preference at any time. This preference is available on the AccurioPro Preferences dialog (AccurioPro > Preferences). 

If AccurioPro is no longer prompting you to confirm which data file to use, but you would like a document's DDF to use a different data file, you can simply select the new data file. There are several ways to do this. First, open the document. Then, apply one of the following actions:

• Open the AccurioPro panel menu and choose Select Data File.
• Open the AccurioPro menu and choose Setup > Select Data File.
• Open the Data Source Definitions (DDF) dialog, confirm the Current DDF pop-up menu is displaying the DDF that you wish to edit, and then click the Select button (which is on the bottom right corner of the dialog).
