How to set a flow variable of type array using a script

[suvro]

Hi,

I am using a flow for a catalog item, where there is a variable which contains an object which has an array.

And I need to generate approvals dynamically based on the length of the array. 

So I though of creating a flow variable of array type and using set flow variable I will be able to parse that variable and set the variable with the array, but I do not see any option of wrting a script. The option appears for string type of variable. Any pointers will be appreciated thanks.

Hi Suvro,
You might have to create a custom action to make this work.

Hi @suvro 

May you use a List Collector in the Catalog Item and a For Each in the Flow.

This is the best and recommended approach.

Catalog Item

Create the variable as:

• Type: List Collector
• Reference: the appropriate approval table

A List Collector already returns a list of sys_ids, which Flow Designer treats as an Array.

Flow Designer

• Use the catalog variable directly
• Add a For Each action
• Iterate over the List Collector values
• Inside the loop, use Create Approval
• Approver = current item from the loop
