Hi Madhu Sudan,
Pricing Procedure as you know is one and the same as calculation schema.
To administer the PP i.e. Determination of Calculation Schema for PO you will have to go to the transaction SPRO---SAP Reference IMG
Follow the node
Materials Management-Purchasing-Conditions-Define Price Determination Process-Define Calculation Schema.
Once you are there In the calculation schema (pricing procedure), you specify which condition types are to be taken into account in which sequence
Now coming to your query,
1) Assignment a Calculation Schema (PP) to Doc type
-- Remember It is not possible to assign PP to Doc type
2) Trigerring of PP in PO
-- Follow these underwritten simple steps:
i.  Define a schema group for vendor under the node> Materials Management-Purchasing-Conditions-Define Price Determination Process-Define Schema group. You will have to assign this same schema group in the relevant vendor master record.
ii. Define a schema group for Purchasing organisation under the node> Materials Management-Purchasing-Conditions-Define Price Determination Process-Define Schema group. & assign it to the relevant Purchasing Organisation in the same step.
iii. Once this is done you have to Determine Calculation Schema for Standard Purchase Order under the node>Materials Management-Purchasing-Conditions-Define Price Determination Process-Define Schema Determination. In this step you assign Calculation Schema to a combination of Schema Group (Purchasing Organisation) & Schema Group (Vendor).
iv. Conclusion: During the time of making a PO; Shema Group of Vendor is picked from the relevant Vendor Master Record, Schema Group of Purchasing Organisation is picked from Customisation (where you assigned it) & A Calculation Schema is triggered for the combination of these two Schema Groups (PP that you defined in step iii)
Hope this explains it, for better understanding please read the IMG activity documentation for each activity.
For any further doubts please reply.
