Blog I will provide a how to guide on enabling data encryption for RFC connections to ABAP back ends. How to avoid problems Do only install SAP Cryptographic Library. SAP Cryptographic Library and libsapsecure will not work in parallel. You have to setup SNC before you can activate SNC with the parameter sncenable 1. Preparation. Please follow these steps of the SAP Documentation to install the SAP Cryptographic Library 1. Download the SAP Cryptographic Library from http service. Download SAP Cryptographic Software. Install the SAP Cryptographic Library on the SAP Web AS. Enter the RFC Destination name and Target Host name like below and hit Save. Test the connection by clicking on Connection Test button in the application. Dont forget to set the environment variable SECUDIR for the User which runs the SAP ABAP stack. Now you can also set the Profile Parameters for Using SSL or use my Blog Setup HTTPS SSL for the Sneak Preview SAP Net. Weaver 0. 4 ABAP Edition on Windows to do that. Setup SNC on the ABAP Server. First we set the instance parameter sncidentityas to the distinguished name the server should get. I use CNIDS, OUIT, OCSW, CDE. Dont forget to add p in front of the DN. CNIDS, OUIT, OCSW, CDE. Create SNC SAPCryptolib PSEAfter a restart of your server you can now create the SNC PSE. Start transaction STRUST or STRUSTSSO2 and right click on SNC SAPCryptolib choosing Create You just have to accept the SNC ID which is taken from the instance parameter sncidentityas Please follow the next hint and add a password for the SNC SAPCryptolib PSE To do this double click SNC SAPCryptolib and choose Assign Password Type in a password which can contain letters and numbers Without the password the server would not start when you have set the parameter sncenable to 1 Save the settings. Set additional parameters. With the SNC SAPCryptolib PSE created we can now set this Instance Parameters sncenable 1 sncacceptinsecurerfc 1 sncacceptinsecuregui 1 sncacceptinsecurecpic 1 sncpermitinsecurestart 1 sncdataprotectionmin 1 sncextidlogindiag 1 sncextidloginrfc 1. I have chosen values which will enable you to still connect to the system without encryption. Done that, you have to restart the application server again. Create PSE for RFC Client. Ive decided to use a separate PSE for my RFC Client as described in Scenario 2 Using Individual PSEs for Components. To create this PSE I follow the instructions given in Creating an SNC PSE for the SAP J2. EE Engine. The steps described show an example setup done on my Linux box. To test the connection I use the demo programs coming with SAP Java Connector available at http service. Ive extracted the connector in usrsapjco. Create sec directory for RFC Client PSEMTo store the RFC Client PSE I create a subdirectory sec in usrsapjcodemo zappod cd usrsapjcodemozappod usrsapjcodemo mkdir sec. Now switch to this directory and create the PSE zappod cd sec. Create PSETo run sapgenpse the directory containing the SAP Cryptographic Library libsapcrypto.

Hello everyone, in this SAP Netweaver Gateway tutorial, we will learn how to consume external OData services in SAP Gateway. External OData services means the service which are from 3rd party systems or Non SAP systems. With OData Services Consumption and Integration OSCI SAP has provided the provision of consuming external services. So lets get started. Supported System Version. SAP Net. Weaver Gateway 2. SP6 or higher SAP Net. Weaver 7. 4. 0 SP2 or higher. Business Scenario. In this demo example we are going to consume Northwind OData service from www. You can get the list of available OData services here. Step by Step Procedure. Create an HTTP connection to your external system by creating a RFC connection of type G in SAP  Netweaver Gateway system. Go to t code SM5. Configure RFC Connection. Select HTTP Connections to External Server node and click on Create. Enter the RFC Destination name and Target Host name like below and hit Save 3. Test the connection by clicking on Connection Test button in the application toolbar. You should be able to connect to the server and should see the HTTP Response code as 2. Create SAP System Alias. Create a System Alias for the above created RFC destination. Go to SPRO  SAP Reference IMG and Navigate to this path SAP Netweaver Gateway ODATA Channel Configuration Connection Settings SAP Netweaver Gateway to SAP System Manage SAP System Aliases. Enter SAP System Alias name, Description, RFC Destination and Software Version. Select Local GW and For Local App check box as well. Click on Save to save the entries. Go to transaction IWBEPOCISRVGEN OData ServiceGW Generator for External Data Services. Enter HTTP Destination ODATAORGService Namespace  V2Sxuh. OData. Service Name OData. Model Provider Class ZCLNORTHWINDMPCData Provider Class ZCLNORTHWINDDPCModel Name ZNORTHWINDMDLService Name ZNORTHWINDSRV7. After entering above information hit Execute button to generate the service. After successfully service generation you should see the below screen. Our next step is to activate and register service. Go to IWFNDMAINTSERVICE Activate and Maintain Services. Hit button to add our service. In the below screen enter System Alias NORTHWIND and hit Get Services button. We will get a list of services, select our service and hit Add Selected Services button. In the Add Service popup window, check the details and hit OK button. We have successfully registered the service,now its time to test the service. Go to transaction IWFNDGWCLIENT Gateway Client. Enter the service name and execute.
