Unable to select the value to map in flow designer

[ArpitaVK]

I am working on the flow designer that triggers the Staff change LCE from the Workday payload received. The payload includes New Manager ID and Old Manager ID(both are string inputs to the flow).

There is a lookup record for the New Manager ID and the Old Manager ID on the User table. For Lookup on New Manager ID, I am able to map that value to get the New Manager Name and Title.

But for the Old Manager ID lookup, I am unable to select its reference to map. It looks like the selection has been disabled. 

Can someone help me with this issue?

@Tanushree Maiti, It is a subflow triggered from the Scripted REST resource based on the decision table results. I did that mapping last week, and it works fine. Now, I have to add some inputs to that step so I had to remap everything. This time, I observed that the selection is disabled/greyed out, as in the attached screenshots.

This looks like a Flow Designer UI limitation.

You can first try an instance update/repair to see if it resolves the issue.

If not, using a Run Script step with GlideRecord is the most reliable way to fetch both Old and New Manager details.

The issue has been resolved. I created flow variables for Old Manager Name and Old Manager Title - both of type String. After the Lookup record action for Old Manager ID, I set the flow variables to their corresponding mapping from this lookup action and then used these flow variables to set the values in the Submit Catalog item Request action.
