• Save the whole USR02 table content in the IT_ZUSR02 internal table.

Hi Rahul,

Idocs are nothing but the data containers,ie they carry data from one system to another system with the help of a medium,

The 2 mediums that are avialable are 1. ALE

2.EDI

With the help of these two mediums we exchange the data form on e system and another system.

Regards

Rajesh.
