It worked thank you so much 

I am trying to use API URL as $$HOST/attask/api/v18.0/project/search?status={DE:B Number}&$$QUERYJSON Path: $.data[*].name

We currently have a 'B Number' captured as a plain text field on our project-level custom form for different projects. We’re hoping to display this 'B Number' on an issue-level custom form as a dropdown option, allowing users to select from all the values entered at the project level.

Need help with External Lookup field, we have a custom field called DE:B Number at project level custom forms. Now I am trying to get a external look up field at issue level custom form for users to map existing DE:B Number which is available at project level Any help would be highly appreciated tha...
