Hello,
I`m using a POST request with a JSON throught CL_HTTP_CLIENT.
Faced the following situation:
When xstrlen( jsonx ) <= 1024
http_rc = 200. "OK"
When xstrlen( jsonx ) > 1024
http_rc = 400. "Incorrect data given"
Tried to send the same data not via SAP client - Result 200. "OK"
Instead of client->request->set_data I used client->request->set_сdata, the result is similar, as soon as the string size exceeds 1024 bytes, I get a 400 response.
icm/HTTP/max_request_size_KB - 102400
What could be the error, am I somehow filling in the data incorrectly?
Where can there be size limits for request data?
