How to add a menu item in a multi site setup

Frappe Framework
1

Hello,

I`ve created a custom doctype, and want to add it to the selling menu.
If I follow these steps in my test system everything is fine:

  1. edit config/selling.py
  2. bench migrate
  3. reload the site

Now I want to paste the module in the production system which is a muIti site setup. (One erpnext site with imported data from the old ERP System, and one site used for production.)

After I added the data under ‘./apps/erpnext/erpnext/selling/doctype/[name]’ and followed the steps above,
I don`t get the menu entry in selling.py, although I can find the new doctype if I search, and can also add it to the desktop.

I`ve tried also:

  1. bench --site [site name] migrate
  2. set developer mode in site_config.json and then migrate
    But this does not solve it.

Any help would be greatly appreciated.

Thanks in advance

Guido
