TPOP Using a Quotation 
Use
You can use this function to order a part when the following conditions apply:
● The part cannot be sourced from an internal facility or an external supplier
● A global Available-to-Promise (ATP)/source determination search in SAP Advanced Planning & Optimizer (SAP APO) does not yield a result.
If these conditions are met, you can do the following:
1. Manually select customers, who sometimes act as suppliers and who have this product on stock.
2. The supplier customers are asked whether they can supply the requested quantity to the purchasing customer.
3. When responses are received from the supplier customers, select a subset of eligible supplier customers.
This subset ships the part to the purchasing customer.
The third-party order processing (TPOP) process starts with a customer sales order in SAP Customer Relationship Management (SAP CRM) and sourcing in SAP Advanced Planning & Optimizer (SAP APO). SAP CRM then triggers purchase order creation in Service Parts Management (SPM).

Activities
The supplier shown above is another dealer who needs to be maintained as a vendor in SAP ECC.
...
1. Create sales order (SAP CRM).
You can start the action to manually create a purchase requisition. When a sales order (item) fails to receive a sourcing result from SAP APO, an action could be started manually which creates a purchase requisition (PReq) in SAP ECC MM when the order is saved.
2. Create purchase requisition (SAP ECC).
In SAP ECC, dealers (more precisely, suppliers) who can fulfill the requisition are manually selected.
3. Create requests for quotation (RFQ) with reference to the PReq.
For each dealer, an RFQ is created that references the PReq. The RFQs are issued to the dealers through the normal message output control in SAP ECC.
4. Receive RFQ (Supplier).
5. Issue quotation (Supplier).
6. Receive quotation (SAP ECC).
Quotations from the dealers are received through the portal, or maintained manually by the internal user.
7. Accept quotation or reject quotation (SAP ECC).
A certain subset of quotations is accepted so that the sum of the quotation quantities meets the PReq quantity. The remaining quotations are rejected.
8. Generate subitems with reference to the quotations (SAP CRM).
The accepted quotations are sent back to SAP CRM. For each accepted quotation, a subitem of the original sales order item is created. This subitem carries the dealer as source of supply and the object link to the quotation.
9. Create purchase orders with reference to the quotation (SAP ECC).
After the sales order is saved, purchase orders (POs) are created that reference the quotations. Now, the scenario merges into the normal TPOP scenario.
10. Receive purchase order (Supplier).
