For analysis purposes, the business process, and the scenario implementing this business process have to be described in detail. The Business Object Types used in the scenario and their BAPIs also need to be identified. The BAPIs are atomic modules that can be used to create different scenarios.
The main dilemma with developing BAPIs is:

On the one hand, BAPIs should be developed so that they can be used in different scenarios, and on the other hand, the interface must be clearly structured.

It is important that you do not stipulate in this phase exactly what the signature of the individual BAPIs is to look like. The BAPIs required for the scenario are simply identified, and their functions and the data they require are defined.

The analysis can be divided into three phases:
