+When we want to open a catalog item with details from current record and map it to the opened catalog form then we can use this code.
+
+This UI Action and catalog client script Redirects you to the record producer or catalog item( based on the sys id provided) and auto-populates the fields from the parent record to the catalog item/record producer variables.
+
+1. UI Action
+   Client - true
+   action name - open_item
+   show update - true ( As per your requirement)
+   onClick - openItem();
+   Workspace Form button - true
+   Format for Configurable Workspace - true 
+
+2. Catalog Client script.
+   Type - Onload
+   Applies on catalog item view - true
+   Name - ParseURL
+
+Note : Above UI Action works in Configurable workspace and opens the catalog item/record producer in workspace itself.
