My mind is blown, loading the Customer record, changing 3 fields and then saving it in the UE script, the UE associated with the record being updated does not fire. 😵 It does fire if I edit / save through the UI. I've also started to see an issue "Cannot call method "getParameter" of undefined" for this: var scriptObj = runtime.getCurrentScript(); var f_timeuse = scriptObj.getParameter({name: 'custscript_blt_first_time_use'}); I have N/runtime and have used .getParameter in exactly the same way earlier in the script 😵 I'm really stuck now!
