Fresh for ERPNext, I have installed the latest version.
Seems I cannot create customized modules or workspace, I can define modules but cannot see it. For workspace ,no create button.
Regards
you can create a new workspace by click on +New Button and after that if you want to set its module than go to workspace list, select newly created workspace and add your module over there.
There is no “new” button when i open workspace doctype, not sure whether disable workspace customization for latest version.
