To edit a data source
The Field Selector Dialog Box opens.
Typically, this dialog box is used to customize the column mapping between the TimeLiner and the external project file. For example, if the external file includes Baseline Start and End dates you may want to map them to the Start Date and End Date columns in TimeLiner. Also, if you have added any user columns to TimeLiner, for each link, you must map the data in the external file to the required user columns in TimeLiner, otherwise the user columns will be empty.
