Segregate internal ordered items from purch. order items for the i-pro user

Question

We want to know if there are any Oracle i-Procurement implementations that have segregated the internally ordered items via an Order Management sales order from items ordered on a PO (purchase order). We have considered three possible paths to purse. 1) Table of Contents: this seems to not work because you can only connect a Group at the Category level not item level, 2) Multiple responsibilities one for Inventory and one for drop ship: This is not acceptable to the user. 3) Requisition Template.
We attempted to implement this by creating two i-Pro stores named Main and Inventory Only. Our design defined that these stores be associated with a catalog for each group of item. We interpreted that the "Include items without suppliers in this catalog" flag in the Catalog definition would select those items that are stockable. However, the logic behind this flag does not consider the item attributes/Sourcing Rules set at the ORG level. Our company has two Orgs named INV for inventory and DEV for our service organization. For stockable items the items are coded Inventory Sourced in the DEV item master and the sourcing assigment is linked to a sourcing rule which is internal (that is, get from INV org). The items are coded Supplier Sourced in the INV item master and the sourcing rule is a Blanket. Thus, our inventory items were not included in the the catalog even though they were sourced internally at the DEV org because of the blanket sourcing rule in the INV org.
Thank you, Ned

Meera,
Which version of SBO are you using 2005 or 2007?
I don't think Serial numbers can help in this scenario.  There is no hard allocation or blocking possible using Serial numbers.
This is the Work around I am thinking about.
Set the items to be Batch Managed - On Every Transaction
When performing Goods Receipt, enter the Sales Order Number as the Batch Number
When creating the delivery, using SBO_SP_TransactionNotification we can easily check the Batch of the Item being selected and verify it with the BaseRef of Delivery lines to match with Sales Order number.
If the numbers don't match we can warn user with message, "The items batch reserved for Sales Order xyz"
Even if you make a mistake when entering the batch number same as Sales Order number when doing a goods receipt. It can still be traced and blocked during delivery.
Hint: The Batch table records the Goods Receipt transaction along with the BaseDocument number, Base Ref, etc
If you decide to go this route, I could help you further.
Let me know
