Work with Multi-value lookup fields in Microsoft Flow and SharePoint - Part 1

I was recently working on a requirement to implement Microsoft Flow on a list that had a multi-value lookup field in it. The requirement was to fire a Flow when an item is created in the list and run a loop for each of the value selected in the multi-value lookup field.

At the time of writing this article, multi-value look-up fields are not supported in Microsoft Flow. This means that I could not straight away use the values from this multi-value look-up field and apply a loop.

If you would like to jump to how we can retrive the multi-value lookup column in Flow, here is the second part of the post

The setup :

For this post, I am using a very simple setup, a "LookupRefList" with some 'Colours'  in it and another list "LookupUsedList" which has two fields which lookup data from "LookupRefList"

1) Colour : Single value lookup (just to show the difference in Flow values)
2) Colours : Multi-value lookup

Flow with a single-value lookup field :

We can retrieve values from a single value lookup straight away

Flow setup :

Result :

Multi Value Lookup field : 

When we to fetch the multi-value column in Microsoft flow, the flow runs successfully, however, when you try to see the execution log, you see an error

We cannot straight away use the multi-value look-up  in a apply to each loop.

In the next part of the post, we retrieve multi-value lookup field values.
