Hello, I am trying to modify an existing ReportUnit (RU). I just tried the following way: ResourceDescriptor rd = new ResourceDescriptor(); rd.setWsType(ResourceDescriptor.TYPE_REPORTUNIT ); rd.setUriString("/userFolder/test-1-ru"); ResourceDescriptor ru = repoService.get( rd, null); ru.setLabel("changed label"); repoService.addOrModify( ru, null); This work as I can see the RU with ne new label with the admin console, but when executing it, it make a MalformedURIException. I tried also to put the PROP_REFERENCE_REPORT_URI (don t remember exactly the right name but correct in my code) as explained in the WebServices doc but it still make these errors. Do you have more precise documentation about what options is mandatory to set for every operation we can do to these documents (RU, RU options and so on) especially the modify and create new items. I have the same problem when trying to modify the options for a report unit (the values are never modified). Patrick
