How to connect ABAP system with IDM?

Hi Friends,

Now i am working on IDM and i am a beginner to this area. i want to connect the ABAP backend system with IDM and provision the users to other systems. As a initial step i am trying to get the users from ABAP to the identity center.

Could any one help me on this by providing any documents (step by step solution)? And send me some other documents also like provisioning LDAP, Portal, legacy sytem users using IDM.

Your inputs will be highly appreciated. Its very Urgent.

Thanks & Regards,
