Good evening everybody,

I'm having some trouble with the work summary add item part, i keep getting the following error message: Conversion from Product UoM Hour(s) to Default UoM Unit(s) is not possible as they both belong to different Category!. I looked all over and can't get an answer for this. In two words: In a project in order to manage time estimation on tasks, i need to add an item in the Work summary. For this, i have an employee with HR Settings/Timesheets/Product= Consultant (Product Type= Service, Unit of Sale= Hour(s), Unit of Measure -> UOS Coeff=1, Measure Type= Fixed, Procurement Method=Make to Order & Supply Method= Manufacture) Each time i add an item for a project, when saving i keep getting the above mentioned error message. Any help would be appreciated on this. Thanks in advance for your help guys. Kind regards.
