What is the functionality of the PA module?

PA module is the most important module when it comes to analyzing the
results of the organization.

In this module you basically collect the revenues from the sale order , the
costs from the production order, cost center or internal order and
analyze their results.

The interesting part about this module is that when it collects the costs
and revenues it also collects the characteristics associated with the costs
and revenues and this is what makes it stand out

So for e.g. using PA module you can find out the following:
Profit of a certain product
Profit of a certain product in a certain region
Profit of a certain product in a certain region by a certain customer
Profit of a certain product in a certain region by a certain sales person
And the list can go on in depth

It is one of the most wonderful modules in the SAP
