Connect to SAP Cluster Gateway failed

Question

Hi all,
We have outbound idoc from SAP clusters for further configuration.
We have java applications deployed in IBM WebSphere Application Cluster (WAS_A and WAS_B)
At SAP side, we have 2 SAP instance, CI and DI with ACSC configuration,
For the gateway ports,
1. 3336 for CI
2. 3326 for DI
3. 3316 for ASCS
For outbound idoc, RFC is created to pointing at host and gateway. (ASCS and 3316)
We encountered the following errors
Connection parameters: TYPE=B DEST=SRP.644195 MSHOST=PSRPSVC GROUP=SPACE R3NAME=SRP PCS=1 COMM_CP=1100

If we set RFC pointing at either DI or CI only, it works.  However, it does not work for ASCS.
Please help what else we are missing or any notes can be referred.

Hi DinyBee,
I am assume you have an URL that can get response from your OData Channel Gateway Service. You can test this in your browser. The URL should be something like this: http://gateway.company.com:8000/sap/opu/sdata/sap/APPLICATION/XXXCollection?sap-client=100&$format=xml
If the URL is working, you can setup an Application Connection in your SCC by follow the steps:
1. Select Applications, then go to Application Connection tab
2. Register a new User, with all the correct Server information, remember specify your activation code.
3. After you register the user, at the same Application Connection tab, select your user, and click Properties.
4. Go to Proxy option, and you insert the URL "http://gateway.company.com:8000/sap/opu/sdata/sap/APPLICATION/" into the Application Endpoint. Then click OK.
5. In your iOS application code, you register your Application using the object LiteSUPUserManager, and then get the Application Endpoint by using object LiteSUPAppSetting.
6. Now, your application already got Online in the SUP, and the application also know which URL it should connect to.
7. From now on, you can use object SDMRequestBuilder to build the request, and get the response from the OData Gateway.
This is just a high level steps for you to reference, you should refer to Sybase documentation to get more information about the objects that I mentioned.
Thank you.
