You can refer to this article by Ankur https://www.servicenow.com/community/developer-blog/using-list-collector-in-flow-designer-for-each-l... and store your watchlist users in an array and then update watchlist in catalog tasks.

HI @VIKAS45 ,
I trust you are doing great.
To address this issue, you can use a Script Step in Flow Designer to manually update the Watchlist of the Catalog Task. Here's an example code snippet that demonstrates how you can achieve this:

(function execute(inputs, outputs) {
  var taskID = inputs.task.sys_id; 
  

  var userList = inputs.item.variableName; 

  var taskGR = new GlideRecord('sc_task');
  if (taskGR.get(taskID)) {
    taskGR.watch_list = userList;
    taskGR.update();
  }
})(inputs, outputs);

Hi Amit,

Where Should I write this script in

1)ISubFlow Input and Output

2)In Setting Flow Variables with script

3) Updating Catalog Task Watch_list field with script

4)Action Module in Servicenow

Also what should we select variable Type

[sourav1999]

- Watchlist Users can be set from the Service Catalog Item Variable by creating a business rule on the sc_task table

- The business rule should be a "Before Insert" type -The script should use the current.variables.watchlist_users to get the value of the variable

- The script should set the value of the watchlist_users field to the value of the variable

- The business rule should be activated to take effect
