Hi Ashok,

Instead of the following code.

Map<Id,Account> deleteconn = new Map<Id,Account>();
deleteconn = trigger.oldMap;

Map<Id,Contact> deleteconn = new Map<Id,Contact>();
deleteconn = trigger.oldMap;

Thanks & Regards,

Your trigger is on Contact Object, so trigger.old map will capture all contactIds. Write it on Account object instead.

Hi Ashok,

Instead of the following code.

Map<Id,Account> deleteconn = new Map<Id,Account>();
deleteconn = trigger.oldMap;

Map<Id,Contact> deleteconn = new Map<Id,Contact>();
deleteconn = trigger.oldMap;
