When bulk updating old Opportunities to 'Closed Lost' via Data Loader, some records failed to update with following error -
Required fields are missing: [Custom_PickListField__c]
How can i bypass this error, and update the Opportunity records to 'Closed Lost' ?
Note: These Open Opportunities have a close date way back in the past. Seems like these were created before the Custom_PickListField__c was made required.
