you cannot maintain different pricing procedure 

Since you Assign A Pricing Procedure to a combination of 
Sales area document Pricing Procedure  and Customer Pricing 
Procedure

A pricing procedure is determind by means of doc procedure, 
sales area, and cus pri pro..once determined it is linked 
with the sales area...but cannot be assigned for the 
different mtrls...as there is one procedure that can be 
alloted..but the the conditions can be customised as per 
the requirement..,.also the funda of using pricing 
supplement is diferent which can be attached to that of the 
condition in case of change in the price.

Dear Friend,

You cannot maintain two pricing procedure for two different 
materials becos pricng procedure is a header data.
You can modify your values in the conditions tab of the 
item data. You can exclude or include conditon types( if ii 
is permited in the customisation of pricing procedure) for 
different materials. there by you can achieve a set of 
different condition types for two different materials.

thanks and regards
Siva

in a single sales order you can't maintain two different
pricing procedure. but you can kept two different price for
two different material in Material master data ( Accounting
View) and you can change in Header Condition Data also.
Because Header condition data are flexible and independent.

No, u cannot maintain 2 separate pricing procedure s for sam
e material in single order..but u can change the price
manually by selecting the material and then the conditions
tab....u can also see the changed status as manually later ..

1. it is possible to maintain two pricing procedure for
sales area,hence it is possible to maintain 2 pricing for 2
item from 2 different pricing procedure as the system will
check the pricing in the hierarchy of.....
a) respective pricing procedure.
b)respective condition type.
c) appropriate condition record in the access sequence.

And than the price will be determined
