From the Data Editor's grid, select the transactions from the left-most column in the data grid, right click on your selection, and then select Delete Transaction from the resulting shortcut menu. Datapage+ will then display the Delete Transaction dialog box. Fill out the dialog box and then click OK. Datapage+ will take a brief moment to delete the info from the database and refresh the screen.

Delete Transaction dialog box

Permanent Remove - This check box determines whether or not the actual transaction structure is permanently deleted out of the database.

- If you mark this check box, Datapage+ will completely remove the entire transaction. In this case, the Select Variables list becomes disabled.

- If your clear this check box, Datapage+ will keep the structure intact but will set the specified feature variable values to NULL. In this case, you are allowed to select the affected feature variables from the list.

Important: Even if you have Permanent Remove cleared, this will still remove the data permanently from the database for selected feature variables and transactions even if the structure remains intact.

Select Variables - This list displays all available feature variables. If you're not permanently removing the transaction or transactions, this list becomes available so that you can choose which feature variables will take a NULL value.
