Vikas Menon Apex Batch to insert record in custom object
Hi All,
Require urgent help. I have custom object of dispatch orders . I want to create a batch class which makes a DO based on the Opportunitie's which are have StageName="Closed Won". Please share a general format along with the cron string value which can initiate record creation every 15 mins.
i have a written a code but the record has failed.
thanks
