SAP B1 HANA sdk

Hi experts,

Our company SAP B1 add-on is providing HANA crystal report templates (as .rpt files) so that one can access the report model and provide database credentials to logon to the report and access it. I have pasted the VB code to do connection to Crystal report from our add-on. And it is working fine, if we are providing database credentials from add-on. But as we switch to Cloud HANA version of B1, single sign on feature is being used to log on to SAP. Here we are expecting that , it should connect to crystal report as well without database credentials since SAP will not provide database credentials in cloud environment. But the problem here is that, we are receiving the error as 'Database logon failed' when trying to do the same. Can you please verify the scenario and advise fine solution for this issue. Do we need to change the structure of using reports. Please help.
