BPM and Proxy
I am creating a BPM that will receive an invoice with attachment from a third party system. The attachment will be in PDF form in BASE64 encoding format. The payload together with the attachment will be mapped to the RFC function module structures then will be sent to SAP R/3 via an RFC adapter.
I used a BPM as a receiver of the invoice. I have 3 nodes.
1. Receive payload.
2. Call a proxy program within XI to read and open the attachment then map it to the RFC FM.
3. Call the RFC.
However, I am not able to call the Proxy correctly. But in SXI_MONITOR, I can see that the BPM was called as the receiver.
I am not familiar with Proxy configuration. Can someone walk me through the process of BPM and Proxy?
Please take note that the Proxy is only within XI and not in the ABAP R/3 side.
