SAP PFM - destination in SAP BTP OK, in import data-app not OK

Hello,
we have set up the destination and cloud connector settings for connecting the SAP Product Footprint Management solution on SAP BTP to the S/4HANA on premise system according to the documentation.

The connection check in the SAP BTP destinations (SAP_SUS_IN, SAP_SUS_OUT) area show "connection successful". But when we trigger the app "Import data from SAP S/4HANA" the response is "not connected" and the error message goes: "Set up the destination SAP_SUS_IN in your subaccount."

Any idea how to resolve this issue?

Thanks
