Hi there,
according to the Documentation, mofifying / adding data via ODATA Webservices should be possible.
My Request URL looks like this:
POST api.businesscentral.dynamics.com/.../<Name_of_ published_ Web_Service>
I can GET the data just fine with that link. but when I try the POST, I get the error message

EDIT: working in SaaS environment
Thanks for the help in advance
regards
