go to post Dénes Paczolay · Dec 18, 2018 Hi Robert,Thanks for your answer.I generated a new SOAP service with the wizard (Caché Studio, File/New... General/Web Service). The created WSDL of the new Web Service doesn't contain fault tags either. There is no checkbox or other input field for fault options on wizard page.I'm using:Cache' Studio Client 2017.2.2 Build 865Server Cache for Windows (x86-64) 2017.2.2 (Build 865U_SU)Do you have further ideas?Regards,Dénes
