Task 1: IVN Scanner (for Detail Extractor Job)

The IVNScanner task determines whether index data has been verified before letting the Detail Extractor job continue processing. This task is primarily intended for applications with a customized verification/audit application.

IVNScanner looks for a date processed in the Date Accepted (or Date Rejected) column in the volumes table. A volume is a data file that has been successfully processed by the Indexer job and referenced in the volumes table. The Indexer job must run before Detail Extractor. The Detail Extractor job processes one indexed volume at a time until IVNScanner finds no more newly indexed volumes listed in the volumes table.

If you selected "Intercept to Verify" in the Action on Index Volume option when configuring the AutoIndexVolAccept task in the Indexer job, you must use your customized verfication/audit application to either accept or reject the indexed data before the Detail Extractor job can upload data from the indexed data input file. (You can optionally choose to run the job when the volume is rejected; this is useful in a test environment only.)

IVNScanner Task Input:	IVNScanner Task Output:
· A date processed value in the Date Accepted or the Date Rejected columns in the volumes table	· (None)

IVNScanner Task Configuration
Field	What to enter/select
Index Volume Status	Specifies that the job can proceed when a date appears in either the Date Accepted or Date Rejected column in the volumes table.
	Accepted	(Default) Choose this option if you do not have custom verification/audit application or if you have one and you want to run the job only after a volume has been approved. If you choose this option, IVNScanner looks for a date in the Date Accepted column; if it contains a date, the Detail Extractor job proceeds.
	Rejected	Use this setting to continue the job if a volume has been rejected in the custom verification application (use this option for testing purposes only). If you choose this option, IVNScanner looks for a date in the Date Rejected column; if it finds a date, the job proceeds.
Scan Starting From (Number of Days)	Specify how many previous days’ volumes to scan for; IVNScanner selects any volumes indexed on or between the current date and the number of days ago you specify.
