Data transfer between PCK and SAP PI

Hi,

We have a scenario where the data is send from PCK to SAP PI. But there is no sender agreement.

The interface is woking fine in production. But I would like to know how the interface is triggered in PI.

When I check the dynamic configuration I could see filename. So is it possible to send the data as file to SAP PI from PCK without any sender agreement?

Thanks and Regards
