Dear Experts,
API_INBOUND_DELIVERY_SRV;v=0002/A_InbDeliveryHeader(ref: https://api.sap.com/api/API_INBOUND_DELIVERY_SRV_0002) in SAP_COM_0106 scenario from BTP system to Public cloud system we call the service with the Post method. Naturally, from time to time, we get errors originating from the purchase document. When we want to see the details of the errors, it states that the service user we created is not authorized. How should we go about this?
I am sharing the screenshots below:


Thanks!
