How does Sales Price schema is picked

Hi,

I am little surprised how do the system picks Sales Price schema.

Even i have not maintained Assign pricing type to organisational level.

But while creating article master i am getting Net Sales Price,Gross Sales Price ,Final Price as 408,which is the value in enter in Purchasing view to Net Price.

I am surprised how system picks pricing procedure WWS001.

Also when i see into analysis part,it shows Condition type EKNN is manually entered.

How does EKNN picks value

Thanks,

Pradeep M
