Biplab,
In VK11, you create a condition record for price condition type ZK10.
Go to table level, here SAP "stores" the condition records and "assigns" those to the orders, where applicable.
SE16N
input table A670
in the initial screen, give condition type = ZK10 and F8
You will see the link -
Application, Condition type, variable key (fields from the condition table), Valid To and From, condition record no.
This is how system links condition type with condition table,
for every different condition type.
For other condition types, do the same exercise with A###

Added: This is the same concept for all functionalities (output, account assignment etc. etc.) which use condition technique.
