I haven't done this (yet) but I know it must be doable via the Management API. Unfortunately, the right examples are still missing from this page: QlikView Management API - Getting Started and Examples
Maybe we can invite jbc for a comment on the availability of further examples?
thanks. Looks like i have to use c#, as you told already.
Did already some stuff with the API. Found this Re: QMS API Creating a new task .In combination with GetDocumentenTask(documentTaskID Guid, documentTaskScope) I think I will be able to find a solution.
