CA IDMS/DC Mapping Facility › Online Mapping Facility › File Field Selection Screen

File Field Selection Screen

The File Field Selection screen, shown below, enables you to select external record elements for inclusion in the map definition and for editing on the File Field Edit screen. Fields not included in the map definition are not mapped in or mapped out at runtime.

The File Field Selection screen lists all of the fields in the external record. If the record contains more fields than fit on the screen, MAPB builds additional pages to accommodate all the fields. You can display other pages of the screen by specifying a page or by pressing ENTER to display the next page.

You select fields on the File Field Selection screen by keying a nonblank, non-underscore character (except the D character) at the underscore below the SELECT prompt that corresponds to the desired field. You cannot select both a group field and any of its subordinate-level fields.

By selecting an external field for inclusion in the map, you also select it for editing on the File Field Edit screen, displayed later in the map definition. Once a field has been selected and edited, you can again use the File Field Selection screen to reselect the field for editing or to deselect the field from the map definition.

Batch Considerations

Specific fields on the screen are described below:

• SELECT specifies that the corresponding record field is to be included in the map definition. To select a field, key a nonblank, non-underscore character (except the D character) at the underscore below the SELECT prompt that corresponds to the desired field. You cannot select both a group field and any of its subordinate-level fields.

  Selecting a field also selects it for editing on the File Field Edit screen. To reselect a field after it has been edited, key another nonblank, non-underscore character (except for D) over the X.

  To deselect a selected field, key a D, underscore, or blank over the X.
