+Show Open Incident of caller
+
+Script Type: UI Macro
+
+Goal: In Form view caller can see what are the open incident of that particular caller.
+
+Walk through of code: So for this use case a new macro will be added to the caller field,  when it is triggered it will open a new popup window where it will show the list of particular caller which are all open incident.So for this a new UImacro have been used in that a new list icon have been rendered from the db_image table and inside that a showopentckts() function this will get the current caller and then add the query to filter out the list of open incident and then open a popup to show the list of that particular caller which are all open(other than Closed and Cancelled).
+
+Note: To inherite the UI Macro in that particular field (Caller) we need to add the attribute in the Dictionary Entry = ref_contributions=caller_inc_lists [ref_contributions="name of the macro"]
