Hello Experts,
I'm new user of SCN so at the beginning please forgive me if I'll made any mistakes in writing on that forum 
My problem is that I have to configure ID Type drop-down list in the Item details of Service Oder as well as Installation/Dismantle drop-down list. My client's request is to hide some of the positions which are placed on that lists. I'm searching at the Customizing place where I can define that list but I have no idea where it may be. My request to you is can you help me and give me any hints where in the SPRO it may be? I've attatched screenshoots to show what exactly I want to edit.
Thank for all responses and have a nice day,
Mat
