Using the metadata files for DocuWare Import module the following error appears:
The target file cabinet must not be overrriden by the FileCabinet command of DocuWare Control. Stored into default documents tray [...]

The reason is the the DocuWare Import configuration where the metadata is selected is defined to store the file in one existing file cabinet and it is defined too in the metadata file.

Define a Document Tray in the import configuration if the FileCabinet command is already defined in the metadata file (.dwcontrol).
