In logistic for purchase order data extraction we have three info sources like Header level, Schedule line level and Item level Information. What the difference between these three levels
header->item->schedule: every level have deeper information related to the document structure...header mainly refers to EKKO, item to EKPO, schedule to EKET tables...
Hope it helps!

Phani, Why we have three tables in r/3...hdr,item and sced?... in the same way sap is given theee level datasources...depend how you can use it in your appls..
Yes, when I said 'deeper' I meant more granularity (to have a better idea, look into maintenance screen of every datasource in LBWE...here you can perfectly understand that scl datasource takes data not only from eket, but also from ekko and ekpo !)...every deeper level has its own typical info plus the info coming from lhe higher level !!
You have to choose the level that is needed for your requirement and avoid unuseful info..
Assume u place an order for materials from a company. This one order becomes the <i><b>order header</b></i>. In this order there might be 10 different materials. So each of these materials become <i><b>one line item</b></i> of the order.
If the qty ordered for one of these materials is 100 units. and the company has a policy to deliver 20 units on the first day, 50 units after a week and the rest after some time frame. This further split of each line item becomes the <i><b>schedule lines</b>.
