External Lookup when the dependency is multi-select (array)

[_Manish_Singh]

Hello

I am using External Lookup to dynamically display options in the Tech Platforms field. However, the lookup works correctly only when a single value is entered in the Domain Lines field. It shows no results when multiple values are inserted (screenshots below). Is there a way to make it work with multiple values selected?

1) Single selection:

2) Multi Selection:

I understand that multi-select returns an array which cannot be used as a dependency. However, I want to ask if anyone has resolved an issue like this before. 

My Base URL: $$HOST/attask/api/v19.0/PORT/search?fields=DE:Tech Platforms and Digital Solutions&name={DE:Select Domain Lines}&name_Mod=in


Your help is truly appreciated!

Hi @_Manish_Singh, 

Thank you for your question! As you mentioned, the issue here is that when multiple values are selected, the field returns an array (eg. ["Partner Sales", "Sales Support"]). The "name_Mod=in" parameter in the API call cannot handle the array format directly as it expects a single value.

Recently there was a defect for a similar problem that our Engineering team was able to solve. I would recommend submitting a support ticket for this so that we can dive into it a little deeper and reach out to the Engineering team.
