EAM save workorder > 'Scheduled date...... invalid'

Hi All,

I'm new to EAM and our company is preparing a POC for a customer, we are using a vision environment. My issue is that when I create a workorder and save or apply, I receive the error 'Scheduled date (dd-mm-yyyy) is invalid'. When I'm using older dates, 2012 and earlier, no error occurs.

This must have something to do with undefined/not opened calendar periods. I checked all calanders purchasing, inventory etc. and this is (now) fine. As far is I could see this issue is caused by the work calander, but also adjusting the 'to date' to a future date (and rebuilding it using the appropriate conc.request) did not help.e
