Did you do what is said in the error message ?
Processing Error. More details in WS Error Log (transaction SRT_UTIL) by selection with UTC timestamp 20140919041733
And what did you see there ? Any further messages ?
The message says it is a processing error and comes from SAP, therefore SOAP testing tool (whic one are you using ?) is working correct.
I suspect some wrong data in the request, but you wil have to follow the instructions first and let us know the result.
