Project
This includes all the data of an application that is to be transferred to the SAP system.
The project will consist of a Subproject and a Business Object (object). One project can have several subprojects assigned to it.
Subproject
This is an organisational unit assigned to a Project. A subproject can have a number of different objects.
Object
This is a Business Object derived from the business point of view, which is sued to transfer the data to the SAP system.
An object consists of a number of different components like tables, structures for the data transfer, relationship between the data at table and field level and field assignments for conversion of data.
An object is assigned to a Subproject. Customer master, material master etc are examples of objects.
I guess this is fine!
