Summary:

Hi ,
We have a requirement where we are trying are to send multiple bulk export of data(AP,AR,GL) using a custom ESS job set.
In that , we know there is call back event is available for the ESS- job, but do we have a same for ESS-Job set ? Because we are trying combine all the custom BIP- ESS job into a ESS job set, so that once all the export are over, the actual process will be handled at OIC.
