I tried to change field “Creation Document Type” from Select to Link datatype in Serial No DocType because I want to change field “Creation Document No” to Dynamic Link based on the “Creation Document Type”. I also change its options to DocType. When I saved, it showed “Fieldtype cannot be changed from Select to Link in row 14”.
Thanks your reply. If I set creation documention no to dynamic link, I can open this no in serial No form directly. Actually I did this change successfully in a test version, but when I tried to do same thing on official one, it had the issueI mentioned.
