MM pricing schema

Question

Hi Friends,
Can anyone provide me a real good material but easy to understand how MM pricing schema works? I need to understand the functions, controls and dependancies of all the fields that are used in a schema.
Thanks for your help.

hi,
CALCULATION SCHEMA:
In the calculation schema (pricing procedure), you specify which condition types are to be taken into account in which sequence.
In the price (or cost) determination process, the SAP System automatically determines which calculation schema is valid for a business transaction and takes into account, one after another, the condition types it contains.
MENU PATH:
SPRO > IMG > MATERIAL MANAGEMENT > PURCHASING > CONDITIONS > DEFINE PRICE DETERMINATION PROCESS > DEFINE CALCULATION SCHEMA.
SCHEMA GROUP:
These allow you to group together purchasing organizations that use the same calculation schema.
You can also use them to group together vendors for whom the same calculation schema is valid.
MENU PATH:
SPRO > IMG > MATERIAL MANAGEMENT > PURCHASING > CONDITIONS > DEFINE PRICE DETERMINATION PROCESS > DEFINE SCHEMA GROUP.
in this step we have to configure:
1> SHEMA GROUP FOR VENDOR.
2> SCHEMA GROUP FOR PURCHASING ORGANIZATION.
3> ASSIGNMENT OF SCHEMA GROUP TO PURCHAING ORGANIZATION.
SCHEMA DETERMINATION:
In this step, you assign purchasing transactions and processes to a calculation schema; that is, you specify the cases in which a certain schema is used.
For standard purchase orders
(depending on the schema group of the vendor and the purchasing organization)
For stock transport orders
(depending on the supplying plant, the document type and the schema group of the purchasing organization)
For market price determination
(depending on the purchasing organization)
That is, for each purchasing organization, a separate calculation schema can apply for the determination of the market price.
MENU PATH:
SPRO > IMG > MATERIAL MANAGEMENT > PURCHASING > CONDITIONS > DEFINE PRICE DETERMINATION PROCESS > DEFINE SCHEMA DETERMINATION.
here we have to assign the purchase organization schema and vendor schema wwith the pricing procedure.
beside this we have to assign the vendor schema to vandor master also in purchasing data.
