Hi Emre,
Please go to Manage->Settings->Departments-Add Department. You get the "Adding New Department" Tab. On this tab, at the bottom left hand corner we have "Adisyon ....." and the next line "Siparis ..." in English version 2.86. Sorry I can not type Turkish on an English Keyboard. I am guessing the two lines are asking the operator to enter "Ticket Numberator" and "Order Numerator" fields. Just a suggestion, can you put "*" in red when the Edit field can not be blank?
Thank you very much.
Wawan.
