Unable to convert BEx workbook

Hi all,

I have enabled 'BEx Workbook Conversion Settings' in Advanced Analysis v1.4. I then select a BEx workbook on my BW system using the menu option 'Convert BEx Workbook' under the 'Analysis' option. From here on nothing happens and I can't figure out why. The workbook never opens.

The log files doesn't provide me with anything specific to this problem. On the backend we have BW 7.3.

Any ideas?
