is possible to find where is this method call and remove it? i did search through all BPM but no luck, is there still any method can search or any solutions?

Which version are you currently using? Could you please share the details of the error? Also, try running a trace—it will help identify which method is being triggered

Have you restarted the app server?

Thanks for response,
Yes i did restart server, i just think since this was clear state its come from the customization coding method called, i had try my best to search overall on screen customization and off all BPM and even try on base mode, the weird things same error still happen.
Could be suspect something crush the dll file in epicor server folder instead, or have any idea can lookup in sql to search the said method wrongly place or so.
