Oracle PO: Create Release against Blanket PO

We have 3 basic choices for the requisitions created by this process:
1. Release against a blanket PO
2. Autocreate into POs
3. Release as standard PO (but you must have a quotation to use instead of a blanket -- pricing has to come from one or the other).                                                                                                                               

The general process for release against a blanket (or quotation) is:
 1. Create a blanket PO with lines for all parts to be sourced. Enter a price for each line. (Or, enter a quotation).
2. Define a sourcing rule (Purchasing > Supply Base > Sourcing Rules)
Enter a name for the sourcing rule.
Org = your org name
Type = buy from
Supplier = name of supplier on blanket PO or quotation.
Supplier site = name of supplier site on blanket PO or quotation.
Allocation = 100% (must be 100%)
3. Assign the sourcing rule to an Assignment Set (Purchasing > Supply Base > Assign Sourcing Rules)
Enter an Assignment Set Name (for example "MRP Planned Items"
Assigned To (I usually pick Item/Organization)
Org = your inventory org code
Item/Category = part being sourced
Type = sourcing rule
Sourcing Rule = name you created in Step 2
4. You must then enter this Assignment Set Name at the responsibility level for the system profile option MRP: Default Sourcing Assignment Set.
5. Create Approved Supplier List
Upper half of screen:
Type = Item

Enter Item Number
Lower half of screen:
Business = direct
Name = name of blanket PO vendor from step #1
Site = site of vendor from step #1 (must be same site as defined in step #2)
Status - changed to "approved".
Global = no
Owning org = your inventory org name


Click on Attributes button
Enter Purchasing UOM (required)
Select release method:
Automatic release (no review)
Automatic release with review
Release using Autocreate (for greatest control)
Sequence = 1
Type = either Blanket or Quotation
Blanket Number & Line Number
Blanket Status (blanket PO must have been approved).


Support also states that we can also use a quotation to turn a requisition into a standard PO in a similar process, Try entering a quotation in the PO module and reference this instead of Blanket in the Approved Supplier List form
We can also take the approved requisitions and just turn them into POs using the autocreate function. But be sure that  "Approve Purchase Requisitions" as one of the functions on the Approval Assignments form or the reqs will be "incomplete" instead of "approved" and we cannot then autocreate them onto POs
