How can I re-export times that have already been exported to Bexio?

If times have already been exported to the Bexio project, you simply need to set the status of the times to "not yet exported". To do this, filter the relevant project times in the Builder and also activate the "Export status" filter, which you should set to "already exported".  Then, using the “Export” dropdown, select the option “Mark all as not exported to Bexio”. You can then re-export the times to Bexio via the export dropdown.

However, please ensure that the times are removed from the Bexio project beforehand, as otherwise duplicates may occur.
