OK,
this wasn't clear to me. I spoke about SOAP since this is the technique currently applied in our company.
I heard about REST but since I'm not in the IT department of our company I dind't care about this.
Neither REST nor SOAP are mentioned in the manual, maybe it could be added for people
like me with a certain half knowledge

So I will check more in detail how REST works in
general and within RA and if it fits my demands (it probably will).
Thank you very much.
