How To Set Current.due_date Default Value Service Now

The Dictionary Entry Records & Default Values

In ServiceNow, you tin can default field values to better automation efforts in your environment.

Every field on every table, is a Dictionary Entry in ServiceNow.

When yous're looking at a class, that form is contained of fields. Those fields are all configurable as "columns" on a tabular array. Every ane of those fields, is easily referenced back to the Lexicon Entry [sys_dictionary] table.

There are several important fields on the Dictionary entry record.

These fields include whether or not the field is active, whether it's mandatory, read-only, what table it lives on, sure attributes, etc.

Ane of these very important fields is the "Default Value" field. The "Default Value" field is under the "Default Value" tab.

In the Default Value field, you tin use JavaScript to set the value of that field.

Returning A Dynamic Default Value

For example, information technology probably makes sense to set the "Caller" field as the user that is submitting an incident.

Y'all can even go further than this. You tin can write queries in a business concern rule for example, that returns a value to automatically set in that field.

That'southward exactly what the out of box "caller_id" field on the Incident table does. It calls a business organisation rule part and returns the users value, to automatically populate.

You can either utilise a "Dynamic default value" which calls a function in a business organization dominion, or yous can just use some JavaScript to set the value direct.

It actually depends on whether or non y'all want to render a value immediately, or if yous demand to interact with a table in ServiceNow – and return a value from a query.

Hither is what the referenced record looks like, that connects the lexicon entry to the concern dominion.

The "Script" and the "Reference Script" values need to be populated in order for this to piece of work properly.

Y'all need to populate the "Script" with the total function name of the function that'southward returning a value in the business organization rule. Brand sure the cheque the "Agile" checkbox too.

Below is what ServiceNow uses to get the current user, to populate the Caller on every incident.

So here is a benefit of using a query, to return a value. It's a more custom fashion to get a value, if a single line of JavaScript won't work.

Render A Value Using JavaScript or GlideSystem

This is the more mutual utilize instance, in my stance.

Information technology'southward more than frequent that you're going to write a piece of JavaScript as a default value, than to write a business rule to render a value from query.

return value with javascript at dictionary entry

If you're familiar with the ServiceNow Glide System, you can utilise that to auto-populate a value with it.

For case, have any Date/Time field in ServiceNow that tracks the "Opened at" value.

You don't desire a user to change this value, nor do y'all want the user to ever populate this value.

It should be auto populated one single time then never updated again.

To accomplish this, you don't need to write a client script or business rule. You can only set a Default Value that will piece of work every time. Each fourth dimension information technology's referenced, when a tape is created, the arrangement calculates the default value at the dictionary level.

The above value will render the current engagement and time, and ready that equally the value of the field – automatically.

When y'all're using JavaScript to set a field value, you only need to prepend the Javascript, with "javascript:" {enter JavaScript here}

For example, y'all'd utilise the post-obit: setting a user id value as opened by user

Have the above case of wanting to set a value for the "opened_by" user on table.

We will e'er want to fix the "opened_by" field to be the value of the user that is submitting the record, on insert.

And then to capture that value and ready it, we use the post-obit:

javascript: gs.getUserID();

This machine populates the value in the field, without any need for transmission intervention.

There are endless opportunities when using JavaScript and the GlideSystem to populate field values.

Let us know how y'all're using Default Values at the dictionary level beneath.
