About the pricing procedure of purchasing order

Question

Hello friends,
can anyone tell me about the pricing procedure,conditions & texation of Purchase order?
and hoew to maintain all those term in Customisation?

Answer 1

The Basic thing is Condition Technique. In which there are 
1. Access Sequence 2. Condition Record 3. Condition Type 4. Condition Table. 
A Access Sequence access a Condition Record of a Condition Type in a Condition Table is a  Condition Technique.This is a simple logic 
Here the Condition Type is very important like PB00, PBXX,RA01 etc. 
In the background every Condition Type has its own defition means the purpose of the Condition Type  like, is it for Pricing or Percentage, Quntity base, Accrual Feilds etc is to be defined to work this functions.  Normally we use the existing ones without any risk. But some cases, we have to Create a New Condition Types as per the organisation requirement. 
The Pricing Schema is useful to minimise condition types while mention prices for Vendor on the basis of Pricing Schema which we defined according to organisation requirement. 
The Pricing Schema means the calculations procedure of Condition Type. 
Ex.  RA01 - Discoount % is caclulated on PB00 - Gross Price  means 
RA01 is based on PB00  like that we have to define in the Pricing Schema 
which makes easy to use in real time. 
Here PB00 has the Access Sequence - 0002. 
But RA01 does not have the Access Sequence.Why because it is a dependent on PB00. But both are Condition Types. 
In the system, by default some standard  Scheme will be there at Vendor Schema Group in the Vendor Master Screen means the standard one is assigned which is very lengthy which may fullfil our requirement. But some cases which may not fullfil our requirement, in such we have to define. 
For the configuration, I may not able to explain properly through here but will give some idea. 
Configuration: SPRO - IMG - Material Management - Purchasing - Conditions - Define Price Deternmination Process:
1. Define Access Sequence 
2. Define Condition Type 
3. Defince Calculation Schema:- Here you have to define the Schema - Define Schema group 
1. Define Schema Group vendor 
2. Define Pricing Schema group 
3.  Schema group for Purchase Organisation 
4. Assign Schema group to Purchase Organisation - Define Schema determination 
1.define calculation schema for Standard purchase organisation 
After completion of the Schema Group, we have to assign it to Vendors. 
Then whenever we use any transaction with this Vendor, the concerned  Schema will work as configured by us. 
The Pricing in MM is vast because each Condition have its own importance and each Access Sequence have its own importance. So you need not bother about this. First you learn how to define the Calculation Schema through the above.
