Add users to watchlist via Flow Designer rather than replace existing ones?

Jonathan Demeul — Wed, 13 Oct 2021 07:47:14 GMT

Good day, there is probably a simple solution to this, but in Flow Designer I have created a flow that updates the Watch List on the incident form. What I want to achieve is to add a user to the list of already existing users in the watch list, however when I use my flow it simply clears out any user that was in there and replaces is with just the one user_id I provided. How can I fix this that it adds the user rather than replace all the others?

This replaces all users in the watchlist with a single user. I guess that's what I'm asking the flow to do, but I want to be able to add upon the already exisitng users in the list basically.

Kind regards

Hi @Jonathan Demeulemeester

as you already mentioned a simple data pill based assignment will overwrite the existing list in that field. You have to use then inline script variant.

Please see the answers in the following question, which will point you to the right solution: https://community.servicenow.com/community?id=community_question&sys_id=97846855db81f41023f4a345ca96193c

Another option is preparing a Flow variable and take its value for updating the record:

Hi Jonathan

Try this in your field mapping script

var user1 = fd_data.trigger.current.watch_list; //existing watchlist users.

var user2 = fd_data.trigger.current.caller_id;//modify mapping accordingly.

return user1+','+user2;

I feel stupid but I managed to solve this by looking up the record and replacing the watchlist with the datapill of the current watchlist + the datapill of the User ID:

That solved it.

Hi Maik

I didn't really need to use any scripting whatsoever, I could simple combine the two datapills to update the watchlist.

I was confused by the setup variable step as I didn't understand how/why to use that step as it does not produce an output that's usable to fill the watch list?

Hey Maik,

Sorry I must have missed it? I had my browser tab open and posted my solution.

Thanks for the help, I appreciate it.

can you explain your solution for this problem step by step?

Conversely, what happens if you want to remove a user from the list?
