Dynamic List on Catalog Item (For Example a Visitorlist)

[Meloper]

I'm searching for an Opportunity to create a dynamic List on a Catalog Item.

Usecase:

For every Visitor hast to be 4 Variables on the Item (First-Name, Name, Date of visit, time ). 

There is no Problem to create this for one User!

BUT

What I am looking for is a solution that allows me to create another line with the same variables by clicking on a "+" or something like that.
I want to be able to enter X number of visitors there.

Then I want to create a separate task for each visitor, which saves the variable values as field values in a table.

So it should be possible for the secretary to fill in 1 item once for e.g. several applicants on one day and thus generate several tasks for the processing of the reception.

It is not the question how I transfer a variable value, but how I can create the dynamic fields on the item?
Does ServiceNow offer a function there?

I would take a look at the multi-row variable set that sounds like it would fit your requirements here.

Simply clever, Thanks.

I've thought too complicated! I leave the article open anyway.

I have three more questions:

1. since when does this MultilineSet exist?
2. is it possible to attach a set to a set?
And most importantly!
3. how can you easily create new records without constantly clicking on "ADD"?

Thank you for your efforts and the great contributions!

I believe this was new in the London release. As far as attached to another variable set, it should work the same way as the rest of the variable sets. I think you'll need to use the button to add rows unless you're working with the API: Scripting the Multi-Row Variable Set
