Workflows provide both Decision and Action widgets. These widgets will often have configurable parameters. In some cases, the value provided can by dynamic. In other words, the value can be based off of variables included in a campaign.

For example, you may have an event campaign. An event campaign will have date defined for the “event”. In a workflow using a “Wait” widget, instead of waiting “6 days”, for example, you may want to say “wait 6 days after the event date”. To do this, you would use a dynamic value.

Examples of dynamic values:
%CAMPAIGN.EVENT_DATE% + 6.days
%CAMPAIGN.EVENT_DATE% – 1.months
%CAMPAIGN.EVENT_DATE% + 45.minutes

%CAMPAIGN.EVENT_DATE% is called a System Defined Field. In this particular case, the System Defined Field is a date value. Only System Defined Fields that are defined as a date values can be used. Using a date driven System Defined Field, you can apply the following formula:

[date System Defined Field] [+-] [digits].[minutes|hours|days|months|years]
