I`m using soapUI in order to mutate a campaign, I want to change the state of a campaign, from ENABLED to PAUSED, but the service is not working, maybe I'm missing a parameter or the campaign's is incorrect, I don´t know, also I'm using objective c, so there is not an API to be easier the communication with the webServices.
I have added a screenshot in order to detect the error easier.
Thanks.

Cheers.
