  • ServiceNow runs your script each time the notification is evaluated.

  • Your script must set answer = true; or answer = false;.

    • true → notification will send

    • false → notification won’t send

  • Write your condition as a small script (answer = true/false;)

  • Use current to access fields (and current.variables.<var_name> for catalog variables)

For example : 

If you want to send only when the caller’s location = "NYC":

 

answer = (current.caller_id.location.name == 'NYC');
 

 

 

 

If this works, please mark it as helpful/accepted — it keeps me motivated and helps others find solutions.

Hi @Anvesha ,

 

Why You Can’t Dot-Walk Variables


* Catalog variables (including Source Table) are stored in the sc_item_option_mtom and sc_item_option tables, not directly on the sc_req_item (RITM) or sc_task.
* That means they don’t behave like normal fields and can’t be dot-walked in advanced conditions.

Backend Field Value for "Source Table" Variable
When you create a variable named source_table (or "Source Table"), the backend stores it as:
* variables.source_table


You can use this syntax in:
* Flow Designer condition builder
* Business Rules (via current.variables.source_table)
* Scripted conditions

 

How to Use in Advanced Conditions
1. If using Flow Designer / Advanced condition:
current.variables.source_table == 'incident'
or for multiple values:
['incident', 'change_request'].indexOf(current.variables.source_table) > -1


2. If in Business Rule (Advanced Condition field):
answer = current.variables.source_table == 'incident';


3. If in Report / Filter Condition (not script-based):
Unfortunately, you cannot dot-walk directly in filter conditions

— you’d need to either


* Promote the variable to a field on the table via "Question → Map to Field", OR
* Use a Scripted Filter / BR that pulls current.variables.source_table into a query.

 

Best Practice
If you know this variable will be used often in filters or conditions:
* Map the variable to a field (e.g., u_source_table) on the target table.
* That way, you can dot-walk and filter normally in list views, reports, and conditions.
