Establishing communication between Backend ABAP and the SAP Cloud Platform Integration (CPI)
This is a scenario we have built for integration between ECC and 2 Financial Institutions using SAP Cloud Platform Integration. In another Blog we will show the configuration between the SAP Cloud Platform Integration and the Banks.
Below we show you the step by step.
In our example the Backend ABAP directly calls the SAP Cloud Platform Integration without using the SAP Cloud Connector
Step 1 – Soamanager Configuration (Backend ABAP)
In the user name field, enter the user and password that has access to the SAP Cloud Platform Integration Tenant.
Step 2 – SMICM Configuration (Backend ABAP)
If you get the error below, the HTTPS protocol is probably not active on your Backend server.
Error when calling SOAP Runtime functions: SRT: Couldn’t create Object: (“ICF Error when creating HTTP client object by Config for URL “https://lXXXX-iflmap.hcisbp.us2.hana.ondemand.com:443/XXXXXX”: ARGUMENT NOT FOUND”)
To establish secure communication between the ECC and the SAP Cloud Platform Integration it is necessary to enable the HTTPS protocol in the ABAP Backend.
Transaction SMICM à Goto à Services
Make sure the HTTPS service is active.To enable the Parameter, place the parameter below in transaction RZ10.
icm/server_port_2 PROT=HTTPS, PORT=4300, TIMEOUT=90, PROCTIMEOUT=1800
Step 3 – Added SAP Cloud Platform Integration Certificate on ABAP Backend Server
You must add the SAP Cloud Platform Integration certificate to establish a secure connection and prevent the error below:
SOAP:1.023 SRT: Processing error in Internet Communication Framework (“ICF error when receiving the response : ICM_HTTP_SSL_ERROR”)
Access the URL of your Tenant SAP Cloud Platform Integration
Save the certificate in your local machine.
Step 4 – Go to STRUSTSSO2 Transaction
Make sure you are in the anonymous option
After this configuration, you must restart ICM.
You are now ready to make calls from your backend to SAP Cloud Platform Integration.
