In Procore, a submittal manager is a person responsible
for overseeing a submittal throughout its lifecycle. If you
create a submittal and have 'Standard' or 'Admin' level permission to
the Submittals tool, your name appears as the 'Submittal Manager' by
default. However, users with 'Admin' level permission to the Submittals tool
have the ability to assign the submittal manager role to any Procore user
who has been granted 'Standard' or 'Admin' level permission to the
Submittals tool (Note: Users with 'Standard' permission do not
have permission to change the submittal manager). The 'Submittal Manager'
field lets you change ownership of a submittal when the person who
created a submittal (or that submittal's current manager) is no
longer a member of the project team.
