The product registration functionality is available only to MyPraim users registered as final users.
In order to access this functionality directly with a MyPraim account that is not a final user, you will need to be invited by the final user (with proper permissions) belonging to the company indicated as final user.
The MyPraim final user should go to the section Company -> Users/Roles on MyPraim:
After doing this, the invited user will be able to select on his MyPraim account the "final user" company (through the drop-down menu at the top right). Finally, he will be able to access the product registration function under the Products menu.
Roles
Notice that on the section Company -> Users/Roles of MyPraim, by clicking on the Roles tab you will see a list of predefined roles with their corresponding Permissions, remember you can create your own customized roles.
