At the end you find a short summary for a SAP GUI based end-user check as well as the front-end related configuration steps

SAP NetWeaver Business Client 3.0

Objective


Required Backend Release and Stack

• Technically the runtime is as well included as of NetWeaver 7.00 SPS 21, „SAP NW 7.00 SAP21“. SAP NetWeaver Business Client 3.0 is planned to be shipped together withenhancement package 5 for SAP ERP 6.0, „SAP ERP 6.05“, and other SAP business suite applications based onenhancement package 2 for SAP NetWeaver 7.0, „SAP NW 7.02“.

Follow the instructions stated in SAP notes1368177 (SAP NWBC 3.0 Released for SAP BAiO Packages and SAP SRM 7.0)1353538 (SAP NetWeaver Business Client 3.0 - Patch Collection)

The SAP NetWeaver Business Client runtime supports the usage of SAP NetWeaver Business Client 3.0 for Desktopas well as the usage of SAP NetWeaver Business Client 3.0 for HTML.


High Level Backend Configuration Steps

SAP NetWeaver Business Client 3.0 Backend Configuration – SAP Crypto Library (1/2)

SAP NetWeaver Business Client 3.0 Backend Configuration – SAP Crypto Library (2/2)

SAP NetWeaver Business Client 3.0 Backend Configuration – System Parameters (1/2)

Depending on your architecture it might be reasonable to distribute the parameters to the default or instance profile(DEFAULT.PFL / <SID>_DVEBMGS<instance-nr.>_<server>,e. g. EH3_DVEBMGS00_BPEHP).In general it is valid to include the parameters in the instance profile.

You can either use transaction RZ10 for maintaining the profiles or editing them directly on OS level – ensure always before edition in transaction RZ10 that you uploaded the current version from the OS level (menu: Utilities > Import profiles > Of active servers)

Distribution of parameters to the default and instance profile

Attention

After maintaining the system parameters you need to restart your system so that the parameters will be taken into account.For Windows servers the service SAP<SID>_<instance-nr.> (e. g. SAPEH3_00) as well needs to be restarted before the SAP application server ABAP is started again.

SAP NetWeaver Business Client 3.0 Backend Configuration – System Parameters (2/2)


Backend Configuration – TX STRUSTSSO2

Others to be created in the same way

All required certificatesare created

The following four certificates must be created:

System PSESNC SAPCryptolibSSL server StandardSSL client SSL Client (Standard)

If you use server signed certificates you will receive some warnings when logging on via SAP NWBC 3.0 but functionality is not affected.

These screenshots show examples of self-signed certificates maintained via right mouse clicks.


Backend Configuration – TX SMICM

• Menu: Goto > Services or [Shift]+[F1] or

Verify in transaction SMICM that https service is activated

• If https is not active, activate the service via menu: Service > Activate

To be able to activate https the SSL server Standard certificate needs to

be created (see previous slide)


Backend Configuration – TX SFW5

Activate in TX SFW5 enterprise business function /KYK/GEN_AIO_SIMPLIFICATION


Backend Configuration – Services, TX SICF 1/3

To make use of SAP NWBC you need to activate various services in TX SICF.

Most important is the so-called cockpit, /sap/bc/nwbc linked to the external alias /nwbc.

The other services are used to enable the framework (especially /sap/public),and to display the various transactions.

Attention If you have already activated part of the node you can activate the entire tree by deactivating and reactivating the upper node. However, you have to update the service tree with the Refresh icon .

Activate Services in TX SICF



Update the specified services in the Internet Communication Frameworks (ICF), for general information see Note 517484.

Activate Services in TX SICF




Backend Configuration – Roles (1/2)

The use of SAP NWBC is for SAP BAiO packages based on ABAP roles. So to be able to use SAP NWBC as a user interface, roles need to be assigned to the logon user.

Within the SAP BAiO packages, the SAP_AIO_* roles delivered initially with SAP ERP 6.0 have been adapted to the delivered scenarios.For enhancement package 3 for SAP ERP 6.0 they start with SAP_BPR_*,for enhancement package 4 for SAP ERP 6.0 they start with SAP_NBPR_*.

Please use either TX SU01 to assign roles to a specific user or PFCG to assign users to specific roles.

Afterwards do not forget to perform the user comparison in TX PFCG for all newly assigned roles!

Usually SAP_[AIO; NBPR]_EMPLOYEE_S + the relevant functional roles should be assigned to the user.Details can be found in the SAP BAiO Business Process Documentation (BPD).

General Information


Backend Configuration – Roles (1/2)

In order to make use of the complete additional PFCG functionality for SAP NWBC 3.0 you need to enhance client independent configuration table with the following value using TX SM30 or directly SM30_SSM_CUST :

Field name: ADD_MENU_DETAILSValue: YES


Backend Configuration – Cockpit (1)

When SAP NWBC 3.0 is connected to an ABAP system, central access point on ABAP side is the so-called cockpit. The call is established via an external alias /nwbc, so that the URL has always the same structure.

This external alias is connected to service /sap/bc/nwbc.

For example with standard scenario:http(s)://<server>.<domain>.<ext>:<port>/nwbcforwards automatically tohttp(s)://<server>.<domain>.<ext>:<port>/sap/bc/nwbc

For further information please have a look at SAP Note 1368177.

SAP NWBC Cockpit


Backend Configuration – Cockpit (2)

To ensure correct communication you need to verify that the error pages handling of logon errors of the cockpit is configured correctly.


Backend Configuration – System Logon

You can define how the logon screen for SAP NWBC should look like and which parameters should be set for the logon process. To do so doubleclick on the respective service node for your cockpit in transaction SICF, choose -> Error Pages -> Logon Errors and then the button Configuration (see previous slide). You can decide wether you want to use the global settings (usually only user and password) or if you want to set further parameters for the logon process. You can find a detailed description for the configuration in http://help.sap.com/saphelp_nw70ehp1/helpdata/en/48/3a0638902131c3e10000000a42189d/content.htm.


Backend Config. – Table NWBC_CFG (1)

Use transaction SE16 or SE16n to create a new client specific table entry in table NWBC_CFG (refer to chapter 4.6 in general SAP NWBC 3.0 documentation):

IDX: Any three characters Cockpit: * Name: BUSINESS_LINE Lang: <empty> Display: <empty> Value: BAiO Cockpit Path: <empty>


Backend Config. – Table NWBC_CFG (2)

Also via table NWBC_CFG you can define a branding image in the lower part of the left navigation panel with a clickable URL behind the image.Therefore make the following entries in table NWBC_CFG via transaction SE16:

Branding image: IDX = any ID, consisting of three charactersCOCKPIT = * (means relevant for all Cockpits)NAME = BRANDING_IMAGEVALUE = URLThe URL must be a link to a picture (JPG or PNG) and it must be ensured that the image can be loaded without authorization having been required.

Branding URL: IDX = any ID, consisting of three charactersCOCKPIT = * (means relevant for all Cockpits)NAME = BRANDING_URLVALUE = URLThe URL can be the corporate portal page of the company which is then loaded.

For the configuration of table NWBC_CFG and the available parameters see also the general documentation for SAP NWBC 3.0, chapter 4.6 Configuration via Table NWBC_CFG.

Some of the settings to be made require deeper knowledge in SAP basis system administration, such as system profile parameters and configuration of SSO.

Therefore it is recommended that the user just check for the correctness of the settings and the system administrator takes care of the correct configuration of these areas.

System parameters:They can easily be checked using TX RSPFPAR uploading the following selection from the clipboard:icm/host_name_fullicm/server_port_*login/*_sso2_ticketsec/libsapsecussf/*ssl/*

Check for “Trust Manager for Single Sign-On with Logon Ticket” configuration – TX STRUSTSSO2The following nodes need to be created:System PSE, SNC SAP Cryptolib, SSL Server Standard, SSL client SSL Client (Standard)

ICM Monitor – Service Display – TX SMICM, Goto - Services: http and https enabled

Switch Framework – TX SFW5: Enterprise Business Funktion /KYK/GEN_AIO_SIMPLIFICATION enabled

Internet Communication Framework – TX SICF: Check that required services are activatedIf services cannot be activated or are not found in the system run transaction SIAC_PUBLISH_ALL_INT to publish them at once

Roles – TX SM30_SSM_CUST + PFCG / SU01:Enable additional details for view SSM_CUST and assign required roles to your user

Additional cockpit configuration – TX SICF:For correct SAP NWBC 3.0 connection to the backend you need to verify that the error pages handling of logon errors of the cockpit is configured correctly:•Radio button System Logon selected and•Configured for Service Specific Settings displaying at least System Messages using protocol Logon via HTTPS
