Unable to select the value to map in flow designer

ArpitaVK — Mon, 27 Apr 2026 09:03:58 GMT

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?

@ArpitaVK

could be a platform limitation.

Did you check ServiceNow docs?

@ArpitaVK

is this a custom flow action or OOTB flow action which you are using?

Hi @ArpitaVK

Just check the trigger condition of the flow and ensure it is triggerng after User Data :Old manager id saved.

Check the time stamp.

@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.
