Extracting data out of SAP with the Access Risk Management agent relies on remotely enabled function modules to access the SAP database. By default, Access Risk Management calls the SAP function module RFC_READ_TABLE. However, SailPoint created a custom function module replacement that is SAP certified called /SAILPOIN/SAIL_READ_TABLE. This module introduces additional security and improvements.
