ABAP Proxy configuration

Hi,

We have found from one of the blog that following are the steps for configuring the ABAP PROXY.

1.Create HTTP connection in the business system.

2.Configuration Business system as local Integration Engine.

3.Connection between Business System and System Landscape Directory

4.Maintaining the SAP J2EE Connection Parameters for LCRSAPRFC and SAPSLDAPI in SAP J2EE engine

As per our understanding the business is the source system i.e., SAP R/3 system.

Can any provide us the documentation on these steps. We need a basic understanding of the above steps.

Thanks & Regards,
