Not able to pull data through hana live app for SAP Invoice and Goods Receipt Reconciliation

Dear Experts,

Need your kind help as I am in the process of setting up HANA live app for SAP Invoice and Goods Receipt Reconciliation

For the same I have installed the following components --
SAP Invoice and Goods Receipt Reconciliation---HCO_HBA_APPS_GRIRM
SAP HANA LIVE for ECC--------------------------HCO_HBA_ECC

I am able to login into hana live app with this link----http://<hostname>:<serviceport>/sap/hba/apps/grircm/WebContent/index.html?sap-ui-language=EN
But I am now facing a problem in accessing the data of ECC backend system through HANA live app which i have installed in hana studio.

I have also made the entries of hostname and service name in ExtensionsMain.js, available in folder js/extensions

But still not able to see any data in hana live app.

Please let me know is there anything needs to be done at backend system to access the data in hana live app.

Requested you to help asap.

Thanks and Regards,
