How to make choice field dependant on reference fieldIssue A choice field dependent on value selected on reference field can be achieved using client scripts as well. But we need both onLoad and onChange client scripts and script rendering may consume to fetch a huge set of choices for each reference values on onload. It is best practice to utilize the available dependent fucntionality in dictionary entry.ResolutionGo to the dictionary of Choice field (eg.test choice)From related links Advanced, Add Dependent Reference field (eg. Company)Now from Dictionary related list, create choices for a 'test choice' field ( choices: test1, test2, test3, test4, test 5, test 6, test 7)Now add Dependent Value for those choices as 'sys_id' of the Reference field value (Eg. Companies: Adobe Systems, Apple, Citrix Systems, Cyberlink) test1: sys_id of 'Adobe systems' test2: sys_id of 'Adobe systems' test3: sys_id of 'Apple' test4: sys_id of 'Apple' test5: sys_id of 'Citrix Systems' test6: sys_id of 'Citrix Systems' test7: sys_id of 'Cyberlink' test3: sys_id of 'Cyberlink' This way when the 'Company' Reference field value is selected, the respective choices will show in 'Test choice' field Company: Adobe systems Test Choice: test1, test 2 Company: Apple Test Choice: test3, test 4 Company: Citrix systems Test Choice: test5, test 6 Company: Cyberlink Test Choice: test3, test7
