The automatic evaluation of mailboxes use some complicated logic to flag a file for evaluation when it has been received but it also makes sure it does not re-evaluate the mailbox even if the evaluation runs again. The manual evaluation does not have this logic built it. In fact it seems to have no logic, as it re-evaluates a file that has been extracted and has an extraction count of 0. This means that the system keeps trying to retrieve the same file which eventually it cannot since the extraction count is 0 and therefore causes a lot of errors. These errors fill up the system and grind the application to a halt. There is no easy was to fix this issue as even if you delete the file from the mailbox, if the system has not gotten to this delete step before the next manual evaluation then the file again will try to be extracted. These complications make it very difficult to employ the manual evaluation since the customer needs to build the exact same logic that Sterling has implemented in their own table structure. This would be a very nice standard offering.
