In Argentina, we had a legal requirement to send a text file using http_post, as a multipart form.
We need to know how we cand send 3 parameters at once (User, password, text file ).
HTML code solves file sent , but we need to develop an application directly on SAP, using ABAP code, without XI-PI.
We reach external service, but IT can not receive attached file, we assume that HTTP_POST method, RFC, etc (we tried all of them) add some lines or characters that are imposible to external service to read.
Does anyone solve it?
