The special features of the "ecat" user selection are as follows:
- "ERP_PDM_NUMBER" and "Price" has to be set! Then export to CAD system is possible. 
- When changing the role the corresponding price column is displayed. 
- When turning on preferred ranges, rows with red status lights are hidden. 
- When moving the mouse over a status light, a tooltip about export possibility is shown. 
- Directories in the index tree are only then green, if number and price is set.
