How to implement field dependency in magento 2 ui component based on an external field value

by |Published May 24, 2022

I have 2 select fields in my form

parent_company_id
salesman_code

I need to show only the salesman which have the same entity value as the selected parent company option.
Since this is not a direct dependency, How can I implement?

Is there any possibility for getting the selected value of parent company ID in the salesman code’s model file?

I tried doing an Ajax call here, not worked.
