Answer 1

Dear SAP11,
Adding to our friends' views here is my attempt;
1)The conditions (condition records)given through [FV11] / [MEK1] / [VK11] will be stored in Condition Tables with key combinations like plant,vendor,P.Orgn etc.
2)In Access Sequence Accesses will be defined with the concerned fields of key combinations.
3)These Acess sequences will be assigned to Condition Types for which we have defined conditions in step1.
4)These Condition Types will be placed in Calculation Schema / Pricing Procedure / Tax Procedure with required a/c keys etc.
5)This Calculation Schema / Pricing Procedure / Tax Procedure will be determined by the combination of Schema Group Vendor and Purchasing Orgn Schema for Calculation Schema and by Sales Area,Cust.Pric.Proc , Document Pric. Proc for Pricing Procedure etc.
                     System while executing Calculation schema it first encounters the Cond Type wherein through the Access Sequence assigned it determines the Accesses thereby fetches the Condition Table and finally Condition Record or Condition stored in that Condition Table.
If it is OK please reward the points else pose question in specific......................
