Dependencies provide an easy way to ensure tags fire in the correct order. However, there may be situations in which a tag should run in response to more specific criteria from another tag, such as after it is viewable or if it experiences an error. In these situations tag based conditions can be used.
A tag based condition is based off of an existing tag in the TMS. They can be used in rules just like any other condition, and can be combined with other conditions within the same rule.
Tag based conditions can be selected at the bottom of the conditions list. First select a tag, and then select the specific condition from the drop down. Depending on the condition you may need to enter additional information, such as a timeout window.
