ABAP Package

What is a 'Package'?

Package is like a Container. Package holds the Objects that we Create in ABAP.
In Real-time Each and Every Object is stored in the Respective Package. ABAP Package can also be called as 'Development Class'.

The Object which is Stored in the ABAP package Only can be Transported from One Client to another.
Note: Here  Client is Development, Quality and Production servers.

What is a 'Local Object'?

'Local Object' is also a Abap Package that already exists by Default with Name '$TMP'.  If we Save any Object in Local Object , it will be  stored in the Package '$TMP'. Objects saved in this Package cannot be Transported from One Client to another Client.

If you want to transport a Object to another Client to another it must be assigned to a ABAP package other than '$TMP'.
