We have a REST webservice that is running on a server, that is of POST type, and accepts data as multipart-form. One of the parameters is a file that is uploaded to the webservice. Other parameters are String type. The webservice returns another file in as a byte-array.
We need sample code in ABAP that demonstrates how such a webservice can be consumed.
To summarize, you have to call our webservice from ABAP, using a sample input file, and storing the returned file somewhere.
I have 6.5 years of experience as ABAPer. I have extensively worked using creation and consumption of Webservices in SAP via ABAP. I am working in very good organisation in IT.
