No measure options in Export Transaction Data to File package

Hi Experts,

I encounter a strange issue in BPC NW 10.

When I use the package "Export Transaction Data to File", there is no measure options in the step "Please select measures".

If I click next, a message pops up and ask to select the measure.

But I cannot select any because there is no option at all.

Please refer to the attachment. Looking forward to your help.

Thanks,

Winson
