For which SAP driver, specifically? I believe the communication TO SAP is usually HTTP-based, and info from SAP often comes in the form of iDocs. I've integrated with SAP UM in the past using CSV files because that's what the SAP folks wanted to give me, but that was a one-way sync from them to IDM.
-- Good luck.

SAP-HCM/HR uses iDoc from SAP to IDM and RFC calls via JCo2/3 to set values in SAP and to perform queries. SAP-UM can use iDocs and RFC from SAP to IDM and also uses JCo2/3 to write to/query SAP SAP-Portal is unidirectional IDM to SAP and uses SPML over HTTP, AKFAIK

JCo2/3 is also known as BAPI. If that helps.

iDoc = Intermediate Document, a text file format to exchange data between SAP and external systems (actually the by far most complicated text file format I've ever run into.)
RFC = Remote Function Call, SAP lingo for RPC (Remote Procedure Call) and their way of calling programming interfaces over network connections, usually on TCP/33xx.
BAPI = Business Application Programming Interface, the endpoints SAP offers to connect and trigger actions
JCo = SAP Java Connector, a Java library implementing RFC calls to SAP BAPIs. Provided by SAP to be used by 3rd party application like IDM. Earlier IDM shims used JCo version 2, all current shims are based on JCo v3.
