Hi All,

I have SAP Cloud Connector installed in my system, i have configured on premise system settings and also i have enabled access to STFC_CONNECTION FM, the same has been configured in SAP HANA Cloud Platform, i have checked the destination and i get a success message on clicking check connection button, but when i develop and deploy RFC based application and run i get the below mentioned error on the screen,

Exception occurred while executing STFC_CONNECTION in system JCoDemoSystem
