missing timesheet report

Dear,

When using the missing timesheet report: Click Home > Reports > Timesheets > Missing timesheets, I always get the following information: “there is no data available”. When looking deeper into this, I also notice that the TmpProjMissingHourReg table is empty.

However, We are able to fill in timesheets, so there should also be data in the missing timesheet reports.

Does anybody know if I have to fill in extra parameters, so the report will show any data?

Thank you in advance

Dimitri
