Field & Form Rules - Use Cases

    The purpose of this document is to bring out a clear understanding of field and form rules by using real time scenario. The sections that follow walk you through the step-by-step procedure of configuring the use cases, along with relevant screenshots.

    List of Use Cases

    Case I:  Add dependency among PickList fields

    Scenario:

    • Creating Country-City-Support Rep dependency.

    • When we choose CountryCity field should automatically populate with available cities of that country.

    • When we choose CitySupport Rep field should automatically populate with available Support Rep in that City.

     
     

    Step 1:

    To handle the above use case, first we need to include fields (Country, City and Support Rep) with appropriate values in Incident Additional Fields and then add those field to any template (say, Default Template), as shown in the below image:

    Step 2:

    • Create a new rule under "On Form Load" event. 

    • As the dependency is being creating under "On Form Load" event, it gets created only when the form is loaded.
    • Choose "Applies to All Users", so that the dependency will be applied to all users (Technician as well as Requester).

    • Choose Rule Execution as "On Create/Edit", so that the dependency will be created on both request create and edit pages.

    • Conditions can be left as empty, since we want the rule to be applied without any conditions (since dependency is applicable in all scenarios).

    • Under Actions, select the action as "Execute Script" and this will provide a link as "Write Custom Script". 

    • Click "Write Custom Script" and this opens a script editor pop up.

    • Go to Dependency Example under Sample Script. Copy the complete code (you can skip comments), paste it to the Script Code area and save the script.

    The Format for dependency object is explained in the below screenshot:

    Here, the dependency should contain a FIELDS array and a VALUES object, where the FIELDS array should contain the fields for which the dependency should be created and where the (i)th element in the array should be depended on (i-1)th element, and so on..  

    Example: The City field options depend on value of Country and the Support Rep field options depend on value of the City field.

     

    The VALUES object should contain field values, as shown in the below image. (NOTE: All the field labels and values are case sensitive)
