Interceptors to populate field values

[vidhya_mouli]

I have a table u_manager_activities_sv and it has two fields u_catagory and u_subcatogory (which are drop down fields). I have to use an interceptor which allows user to choose the values for these fields. Once they choose, the form should auto populate these values in the respective fields (which is now read-only). How do I do this?

you can use url query parameter, in the target url field of the answer object of the interceptor, add: <table.do?>sysparm_query=sys_id=-1&targetfield1=value1^targetfield2=value2...
