How do you create an array field in ServiceNow?

I am still relatively new to SNOW and I do read the documentation and I do search for help in the community. I could not find any help in either placess for this issue. Please forgive me if this is a stupid question but how do you create an array field in ServiceNow, or can you?

I went to Tables and created a custom table and then I went to Dictionary and started creating fields for the new table. Then it came time to create an array and the only field type I could find that I thought might work is Data Structure. 

Data StructureField that allows the selection of one of the following data structures and entry of values to organize particular information in the record.
  • String
  • Boolean
  • Integer
  • Decimal
  • Object
  • Array

I have no idea how to tell the system I want this to be an array. I suspect there may be a way to manipulate this type of field in a script but I need this to be on a form that users can input data into manually. Actually, I will need several array fields on the form for manual entry.

When I add the field to the form it is treated like a single string field. 

I have no problem manipulating arrays in javascript and elsewhere but the arrays were always fields in the database.  

Thanks,

John

You can create a List field which works like array, but it should be linked to a table.

Hi Sanjiv,

Thank you for the suggestion. I don't think that will work for me though. The end game is that via Orchestration another app will have to come in and extract this data. Assuming I can get the data into the list the way I need to I'm not sure how much effort it will take to extract it in the way I need to. 

Normally an array would work here. I'm thinking that instead of putting the data into separate elements of an array field I will have to create separate records in the table where they would all be linked by a common field. 

Thanks again for your help. I will update this again if and when I come up with the right solution.

Thanks,

John
