Hello Team

Our client has provided requirements to us for that we have thought some solutions but firstly I am sharing the requirements over here. Please check with its solution and apart from these if you have any suggestion then please let us know.

Ex. We are dealing with lab management where one person is there who can be the technician and its superior person is the Reviewer but the client asks if whenever he wants to log in with the Technician user should be able to log in with ID/password/Roles (As a technician) and can do the Procedure and whenever the user wants to log in with the Reviewer user should be able to login with ID/password. Roles(As a Reviewer)

So this is how they asked furthermore their asks is Can the system keep the same username from performing multiple role functions on the same sample/test?
For example, if the user has the user roles of technician and reviewer, then that same user can not review the test result he entered as the technician.

Is it possible to have them use their email as their username, and then there will be a drop-down selection with the user roles associated with that email address?

Our technical team has found that customisation can be done but it can be risky as it is breaking Odoo's standard Procedure.

So we are going to propose the idea of purchasing the license.

So please advise us which solution we should provide to them.

Please respond to us as soon as possible as we have to do the live these Project in this month end only.

Waiting for your response
