@vidishaagarwal5 ,

  // Get sys_id of the current record
    var sysId = current.getUniqueValue();
	var tableName = current.getTableName(); 

	// Get the current view name
    var viewName = action.getGlideURI().get("sysparm_view");
    if (!viewName) {
        viewName = "default"; // fallback if no view specified
    }

    // Build Service Portal URL (use your page ID: test)
    var portalPage = gs.getProperty('glide.servlet.uri') + 'sp?id=test&table=' + tableName + '&sys_id=' + sysId + '&view=' + viewName;

    // Redirect user to Service Portal page
    action.setRedirectURL(portalPage);

Above UI action script redirects with sys_id, table, view of record - update it for your use case, place this code under script section of your UI action.

@miftikhar20 it didn't work for me

Yes, it won't. This script works when you want to send data from a record via UI action to the portal page, not the system UI pages.

Anyways, glad you got the required solution.

Thanks @Ravi Gaurav The above code snippet worked for me exactly
