Hi,Subject: Oracle Apps :Order Management PTO,ATO, CTO Currently i am working on PTO they have some PTO type of orders. They call it Custom Config. The Customer may want to order something that requires Picking and Assembling multiple items from Inventory. The example Ram has given below is representative of what they would do now in FACTS.In this example they put Lines 1.1, 2.1, and 3.1 on the Order. However, Line 3.1 is made up by combining lines 1.1 and 2.1They then release the order and it reserves lines 1.1 and 2.1 and backorders line 3.1They then pick lines 1.1 and 2.1 and move them to their Custom Config assembly areaThe item gets assembled.Then they go back into the order and adjust out (delete) lines 1.1 and 2.1They record the item on line 3.1 into InventoryThey release the order again to allocate item on line 3,1 to the orderThey then ship line 3.1 to complete the order.take an example : in an order there r two lines.say 1.1 Catrdige item which not charged for the customersay 2.1 Printer item which is charged.Customer knows only printer but the bill has to have incl catridge. only printer should shipped in this case i got use PTO model. if so BOM is not installed how do i need to do? can anyone help me out ASAP.kalyan
