To access the partner area, you must first contact the person in charge of your partner company. This person is the operational contact. As a reminder, this contact is intended to receive only the first access codes to the partner extranet of your company.
I invite you to get in touch with this person (the operational contact) because he/she can grant you access so that you can complete the information requested in your partner extranet.
As a reminder, only the administrators of your team have an access to the partner extranet. So you are encouraged to change the status of your team member to "administrator" so that he/she can access the partner extranet.
You then have two options: either you give them access to the entire partner extranet, or you specify the modules they can access.
