SAP

You can create SAP environments by providing the necessary connection parameters.

Before creating a SAP environment, you should take a note of the following:

  • Privileges
  • Prerequisites
  • JDBC driver details
  • TLS connection details
  • JDBC connection parameters

Privileges

Privileges given to service account:

  • User type = System
  • User group = SUPER
  • Authorization profile = S_DDIC

Prerequisites

Prerequisite steps for establishing successful connection:

  • Creation of dedicated service account for erwin with Metadata read-only privileges in SAP system
  • Open Firewall connection between SAP and erwin DI application server
  • Get the SAP System Number and Client details

JDBC Driver Details

The SAP JCO driver is not packaged with erwin DI application. Hence, customer must get the JCO driver from their respective SAP team and deploy the same in erwin application server.

The following sapjco files are required:

  • Sapjco.jar
  • Sapjco3.dll

    • Location to place these files

  • Copy sapjco.jar into webinf/lib folder
  • Copy sapjco3.dll copy into windows/system32 folder

The tool connects to the SAP system directly using SAP JCO drivers and not to SAP backend database.

TLS Connection Details

In order to use SSL with the JCO, we will need to:

  • Set up the SAP system for SSL (SNC setup)
  • Create a certificate (X509) for the user
  • Pass the user as $X509CERT$ (check JCO doc)
  • Pass some key from the cert as passwd in the JCO

JCO Connection Parameters

  1. Select Database Type as SAP while creating the environment.

    2. The following connection parameters appear on the right-hand side.
