unable to find these batch jobs

Hi, Iam using NAV 2009. When iam going through the help file i have seen these batch jobs. Combine Shipments Batch Job Delete Invd Blnkt Sales Orders Batch Job Delete Invoiced Sales Orders Batch Job But i dint find these batch jobs. My doubt is where do these batch jobs are there in the navigation pane. Please help me.

All deleting batch jobs are in IT administration → Data Deletion u will get all deletion related jobs, for all respective modules.

But r u sure that u want to combine shipment, because if use that system does not delete the orders automatically.
