I have two separate Sharepoint list: Alerts and TaskQueue. The Alerts list has 2 fields: ‘Title’ (string) and ‘array’ (string), the TaskQueue has ‘Title’ (string) and ‘ok’ (boolean), see screenshot below.

I want to update the TaskQeue’s list items’ field ‘ok’ from FALSE to TRUE when the TaskQueue’s list items ID matches with the Alert’s ‘array’ field.

There is a flow, which iterates the Alerts list, make some other actions and updates the TaskQueue list.

So, for the Alert list item, where Title = ‘one’, I want to update the list items from TaskQueue with 1, 2, 3 ID.
For Title = ‘two’ I want update the TaskQueue list items with ID = 2, 3
and so on.

The length of the arrays can vary, but there is always at least 1. (it is part of a bigger flow, the Alerts list items created based on the TaskQueue list items)

I think, I should use the length of the array and use the ‘Do until’ action, but I can’t figure out how to iterate it.

If the the array has 2 elements, I could pick the first and and second element’s value, than use an ‘Update item’ action, where the ID field could be this value.
