Working with looking up columns on lists with multiselect

[Martin63]

I have 2 list in SharePoint: List two is a copy of one

List one: Task Template

• Has Multiple columns, and 
• 3 lookup Columns (ID, Facility, and Facility number). The Facility and Facility number are additional columns from the lookup ID

List two: Main Roster

• Has multiple columns, and
• 3 lookup Columns

my current flow gets items from list one on specific days and creates those items on list two. My problem - how do i get the multi-select lookup column from list one and create that in the other lookup column in list two? I tried creating an array and but that didn't work

Hello @Martin63 ,

the lookup column expects just the 'Id' of the values in an array, not the full value.

therefore, if you want to update the multiple lookup column based on another lookup column you must filter out only 'Id' from the data provided by the source. You can do that with the 'Select' action, insert the whole lookup column as the input and select only 'Id'. Output of this action will then contain only the id's in an array and you can use it to update the item.
