I get the error valid/from to date when importing licenses which are just connected to an agreement without subscription period or maintenance/support period. I have added agreement name in the import file and now also agreement period. The import wizard is however not relevant to agreement period but only maintenance/support period. I have set Maintenance according to agreement to NO. I have even added agreement period dates in the import file and tried to match them with with maintenance/support period (which is not relevant since there is no maint/support!). I have come a bit closer but now it says "Valid from date has to be bigger than purchase date". Do I really have to set this Valid from-date to the same as Purchase date on all rows?? Seems strange to me.
Hope to get some input on this.
