Overlays

You can create and configure overlays in the Forecast module of WFM Web for Supervisors. Overlays perform the function of factors, and help you track events that might affect interaction volume. For example, use an overlay to include in your forecast the anticipated effect of a sales promotion or a marketing campaign.

This help topic covers the following subjects:

See also the separate help topic Overlays Primer.

Getting Started

Prerequisite: You must have the security permission Overlays before you can create or configure overlays or access the action Find Events in the Historical Data Volumes View. It is assignable in Configuration > Roles > Role Privileges > Forecast Role Privileges.

To use overlays, open the Forecast module in the Modules pane and select Overlays. You can then see a hierarchy of business units (BUs), sites and overlays on the Object pane below.

To manage the list of Overlays, select a BU or a site in the Objects pane.

To edit an overlay, select it in the Objects pane and make changes in the Data pane.

Managing the List of Overlays

You can use toolbar icons or Actions menu commands to manage the overlays:

  1. Select a BU or Site on the Object pane.
    A table in the Data pane lists all current overlays.
  2. Click on a overlay to select its entire row.
  3. Select a command from the Actions menu, or an icon from the toolbar:

Toolbar controls

Type Possible values (Impacting or Redistributing) indicate how the selected overlay will affect forecast values. You can change this in the Properties tab by selecting a type:
  • Calculate Using Specified Initial and Ending Impact (select to specify Impacting)
  • Always Use Entered Distribution or Always Calculate Disregarding Impacts and Distribution (to specify Redistributing)
Usage For each overlay, this column lists the Properties tab choice for type (see above).

Editing an Overlay
