Upto my knowledge we can not touch or see standard code for online BC. We have to check it in 2018 or Onprem environment.
But to answer someone, I want to confirm is there any option to check standard code in online BC without help of NAV2018 or OnPrem env. which may I do not know.
Suppose in worst case, I am using Online BC and I do not have OnPrem or 2018 env. in that case what to do? I want to check code of codeunit 80 or any other object.
Thanks in Advance.
You can use Go To Definition (F12) by creating a temporary subscriber to codeunit 80. For Tables and pages, you can create table extension and page extension to Go To Definition (F12).
Thanks a lot.
