I am very new to ISU modules and i have some questions about the Invoicing job from Batch Job perspective. Lets say that , we run a Invoicing Batch Job named Zinvoicing_job daily, and the batch report shows that they produced total volume of 15,000. But the Business users are claiming that they only recieved 12,000 volume total and 3000 is missing. How can this be reconciled? to see where those 3000 were gone or had error or outsorted etc..Is there a best way to achieve this ? any help would be appreciated.thanks.
