SAP S/4HANA

The EmpowerID SAP S/4HANA connector lets you create, synchronize, and manage SAP S/4HANA user, role/profile and role/profile assignment information in EmpowerID. Imported user information can be managed and synchronized with data in any connected back-end user directories. When EmpowerID inventories SAP S/4HANA, it creates an account in the EmpowerID Identity Warehouse for each SAP S/4HANA user, a group for each SAP S/4HANA role or profile, and assigns group membership to users based on their role or profile memberships in SAP S/4HANA.

Once connected, you can manage this data from EmpowerID in the following ways:

• Account Management

  • Inventory user accounts

  • Create user accounts

  • Update user accounts

  • Enable and Disable user accounts

  • Change user passwords
    
    

• Role Management

  • Inventory roles or profiles as groups

  • Inventory role or profile memberships as group accounts

  • Add and Remove members to and from roles or profiles
    
    

• Attribute Flow
  Users in SAP S/4HANA are inventoried as accounts in EmpowerID. The below table shows the attribute mappings of SAP S/4HANA user attributes to EmpowerID account attributes.

Prerequisites

To connect EmpowerID to SAP, you need an SAP account, and you need to install SAP GUI Server on your EmpowerID Server.

You also need the following from SAP to create your Account Store.

• Host Name of the BAPI endpoint

• Username that is authorized to read from and write to the BAPI

• Password

• App server FQDN

• Instance number

• System ID

Additionally the following conditions must be met:

• Each EmpowerID server used to run workflows or perform inventory functions must have the librfc32.dll assembly copied into the C:\Windows\System32 folder. EmpowerID uses the assembly to perform various SAP processes (inventory, workflows, etc.). You can download the assembly from EmpowerID at the following link: https://dl1.empowerid.com/files/librfc32_64.zip

• For read-only connections, along with access to the below-mentioned tables, the service account needs access to the RFC_READ_TABLE BAPI

• All mandatory fields must not be empty (e.g., LastName, PersNumber)

• The standard tables should have the same structure across all the systems

• The systems should have unique records across all the standard tables. For example, the records should not have any leading or trailing spaces on the Primary Key columns

• The system should be free of any data issues. For example, there should not be any duplicate company codes pointing to the same address number.

• The following network configurations should be in place for connecting to the SAP system:

  • All necessary ports should be open on the server used to connect to the SAP system

  • The host name of the SAP system should be resolvable to an IP address

The SAP proxy account used for the S/4HANA connector needs to have access to the below tables as well as the ability to make the remote procedure calls listed:

As each organization's implementation, practices, and procedures with SAP differs, EmpowerID uses an SAP Data Analysis Utility to ensure the necessary tables can be read and the necessary BAPI's can be invoked. The utility reads from all the same tables as the connector and copies data from those tables into the EmpowerID Identity Warehouse. This provides EmpowerID with the opportunity to review and analyze data in order to modify connector logic before setting up the connection.

When you connect EmpowerID to SAP and configure your SAP Account Store, the first time you run inventory, EmpowerID discovers all of the user accounts in SAP and creates them in the EmpowerID data warehouse. Subsequent inventory runs update any changes occurring since the LastTimeStamp value tracked by the SAP connector.

Install the SAP GUI Server

1. Download and extract the GUI7.3.zip file (or a newer version).

2. Navigate to the GUI7.3\NW_7.0_Presentation_\PRES1\GUI\WINDOWS\WIN32\ folder and run SetupAll.exe.

3. In the installer, select SAP GUI for Windows 7.30 (Compilation 1) (or a newer version), and click Next.

4. Select the target directory where you want to install it and click Next.

5. When it finishes installing, open SAP Logon from the desktop icon.

6. In SAP Logon, click to select the Connections folder, then in the toolbar, click New to create a new system entry.

   Open

   

    

7. In the Create New System Entry wizard that appears, on the first page, click Next, then fill in the System Connection Parameters with values like the following on the second page.

   • Description — ECC

   • Application Server — FQDN of your SAP Server, e.g. sap.mySAPserver.com

   • Instance Number — e.g. 77

   • System ID — e.g. EH9

   • SAProuter String — Leave this field empty.

     Open

     

      

8. Click Finish. The new connection appears in the grid.

    

9. Open File Explorer as Administrator and in the extracted GUI7.3.zip file, navigate to GUI7.3\NW_7.0_Presentation_\PRES1\GUI\WINDOWS\WIN32\system\

10. From that folder, copy the SAP .NET connector file, librfc32.dll and paste it into your C:\Windows\System32 folder.

Create a SAP S/4HANA account store in EmpowerID

1. On the navbar, expand Admin > Applications and Directories and then click Account Stores and Systems.

2. On the Account Stores page, click Create Account Store.

    

3. Under System Types, search for SAP ABAP.

4. Click SAP ABAP to select the type and then click Submit.

    

5. On the SAP S/4HANA Settings page that appears, fill in the following information:

   • Display Name — Enter a name for your account store.

   • Host — Enter the FQDN of your SAP Server

   • User Name — Enter your SAP System Administrator's user name

   • Password — Enter your SAP System Administrator's password

   • SystemNumber — Enter the system number from your SAP account

   • DefaultLanguage —  Enter the two-letter language code

   • Client — Enter the Client ID from your SAP account

   • Is Remote (Requires Cloud Gateway) — This setting appears for account stores with local directories, such as Active Directory, LDAP, SAP, etc. When enabled, this tells EmpowerID to use the Cloud Gateway Connection for that account store. The Cloud Gateway Connection must be installed on an on-premise machine. For installation information, please see Installing the EmpowerID Cloud Gateway Client.

6. If you selected Is Remote (Requires Cloud Gateway), search for and select one or more cloud gateway servers and then click Submit. You will not see this screen if you did not select Is Remote (Requires Cloud Gateway).

    

7. EmpowerID creates the account store and the associated resource system for it. The next step is to configure attribute flow between the account store and EmpowerID.

Now that the attribute flow has been set, the next steps include configuring the account store and enabling EmpowerID to inventory it.

Configure account store settings

1. On the Account Store and Resource System page, click the Account Store tab and then click the pencil icon to put the account store in edit mode.

   
   This opens the edit page for the account store. This page allows you to specify the proxy account EmpowerID is to use to connect to the SAP as well as how you want EmpowerID to handle the user information it discovers during inventory. Settings that can be edited are described in the table below the image.

   
   

2. Edit the account store as needed and then click Save to save your changes.

   Now that everything is configured, you can enable the Account Inbox Permanent Workflow and monitor inventory. Be sure inventory is enabled on the account store settings page.
