    • July 8th, 2013: Fixed typo in step 2 (the description of step  for system alias maintenance) and explained importance of the field system id in this step.

    • July 9th, 2013: According to the hint from Roy I now recommend to activate the flag "for local app"

    • June 26th, 2014:

      • Added the information that the prerequisites are fullfilled automatically when using SAP NetWeaver 7.40.

      • Changed the name SAP NetWeaver Gateway to the new product name SAP Gateway

    • November 27th, 2015: Added hint in the prerequisite section to check profile parameters needed for the SAP Gateway Client

    • September 9th, 2017: Updated links to the most recent online help

    • December 5th, 2017: Changed recommendations with regards to the use of "local app" flag


In the past I have frequently been asked for a quick starter configuration guide for SAP Gateway since the configuration guide does explain all options which might confuse people.


In this document I therefore want to describe the basic configuration steps that have to be performed to activate SAP Gateway if

  1. embedded deployment has been chosen or if

  2. IW_BEP is deployed on the hub or if

  3. SAP NetWeaver 7.40 and higher is used

in these cases the core components for SAP NetWeaver Gateway (GW_CORE, IW_FND and IW_BEP) and any optional backend components are deployed together in the SAP Business Suite backend system or at least IW_BEP is deployed on the hub system which is also a good idea in case you want to set up a hub-based deployment.In case SAP NetWeaver 7.40 is used the software component SAP_GWFND is deployed as part of the SAP Basis which comprises the functionalities of the AddOn's (GW_CORE, IW_FND and IW_BEP).


So this quick starter configuration guide will also help you if you set up a Gateway hub system.


After you have performed these three steps you should be able to develop a service on the hub / embedded system and publish it. You will nevetheless have to perform additional configuration steps later on as described in the configuration guide.



Step 0: Checking some prerequisites


  • AddOns:If the system runs on 7.0, 7.01, 7.02 or 7.31 as a prerequisite you have to deploy at least the following three add-ons IW_BEP, GW_CORE and IW_FND using transaction SAINT. When using SAP NetWeaver 7.40 this step is not necessary since the software component SAP_GWFND is already deployed as part of SAP Basis.

  • Profile parameters:Check whether the following profile parameters are set in the instance profile because otherwise you will later have a problem to start the SAP Gateway Client as described in my blog SSO problem with the SAP Gateway Client /IWFND/GW_CLIENT .

      • login/accept_sso2_ticket = 1

      • login/create_sso2_ticket = 2


Step 1: Activate SAP Gateway


As described in the Online Help you start transaction SPRO and navigate to the Activate or Deactivate SAP NetWeaver Gateway node in the implementation guide (IMG).



Step 2: Create a SAP System Alias


You now have to create a system alias entry that points from the hub system to the backend system. Since you have chosen an embedded deployment you will create a system alias entry LOCAL using the RFC destination NONE.



In order to create one sample entry for a co-deployed system you can enter the following values:


Field Value Remark
SAP System Alias LOCAL
Description Local Gateway
Local GW X
For Local App X

Has to be set since the IW_BEP service implementation resides on the same system in case of co-deployment.

If you use 750 or higher you can use the option "co-deployed" only. ( for more details see my blog How to take advantage of the performance improvements ... )
OData on backend (empty)

Can be used for performance optimization in Hub Deployment where Hub and Backend are running both on 750 and higher

( for more details see my blog How to take advantage of the performance improvements ... )
RFC destination NONE
Software Version DEFAULT
System ID The SID of your backend system (here GWM)
Client The client you are in (here 800)
WS Provider System  (empty)


This is shown as an example in the following screen shot:


You must maintain the field System ID though it is not mandatory. This is because transaction SEGW when being run in the backend selects all system alias entries of the backend system from where it calls the hub using the SID of the backend as a filter. If no value is maintained the system alias will not show up in the list. If only one entry is found it is taken as a default and no dialogue will show up.

Step 3: Create a Gateway Alias


This step is needed to have at least one entry for the Gateway hub in the Service Builder (transaction SEGW) to register services that you are going to develop. 



Please note that this time you have to navigate to a different part in the implementation guide called Gateway Service Enablement that contains the Gateway hub specific customizing settings.


Here you enter the following values


Field Value
Destination System GW_HUB
Client The client you are working in (here 800)
System Alias GWM  (Enter a unique name for the host of SAP NetWeaver Gateway, for example the SID of your system)
RFC Destination NONE


This is shown as an example in the following screen shot.


Step 4: Activate node 'opu'


      1. In a freshly installed system you have to activate the 'opu' node using SICF.

      2. In the following dialogue you have to confirm that all sub nodes shall be activated as well

      3. Press refresh

      4. Expand the node 'opu' again and to check whether the changes have been performed





Step 5: Test Your Settings


You can now test your settings by developing a simple service using the Service Builder (transaction SEGW).



As you can see the name of the destination system of the SAP NetWeaver Gateway alias is shown in the Service Maintanance node in SEGW.


When choosing Maintain in the context menu the Activate and Maintain Service transaction is started on the hub system. Please note that the service has been registered for the system alias LOCAL that you have maintained in step 2.





Step 6: (For Development Systems Only !)



Since this quick starter configuration guide will probably mostly used for development or test systems I would like to recommend to raise the Error Log Level for the error log in IW_BEP and IW_FND.

Use the following transactions to change the settings for the Error Log Level from Secure to Full as shown in the following screen shots:


Backend Error Log --> transaction /n/iwbep/error_log . There from the menu choose Error Log --> Global Configuration





Gateway Server Error Log --> via transaction /n/iwfnd/error_log . There from the menu choose Error Log --> Global Configuration
