For Opportunity record..When i cloned opportunity record and given contact name. The record is similar to the original one. but after create a report to check i found that Primary contact is empty for Cloned record. I want to make populate this one. but i didnt found any where as a field. please any one suggest any trigger for this ?
How are you cloning the record? From the standard page layout, or from Apex / Visualforce? If the latter, all you should need to do is add the Primary Contact field to your query for the existing Opportunity.
