Hi Expert,

I'm going through the below videos for customize fetch action chain for SDP.

As per the video's it showing for customize filter criteria, we need to check the configuration object and then the hookhandler which is inside the configuration object.

I have developed similar application and the same hookhander object is not accessing in my application.

Is the hookhandler is still relevant in javascript action chain because when i search by data in select single i could see filter criteria is working as expected whereas in the video the fetch action was customized
