The Data is coming from a View that is published on TIC, the view is drawing from an Oracle Database.
The Workbook consists of 1 Dimensional View.
I can publish the the data from the View as a dataset with "publish data".
I tried publishing a workbook that has a (local) .xls file as datasource and a simple dimensional view worktab, also this workbook can not be published as workbook and triggers the same error messages.
