You are not authorized to change products

Hello !,

I have an user asking for permission to change product name.

I made some changes to the Menu so now he can access the Products,

but when he tries to edit a Product he gets the message "You are not authorized to change products".

Then I returned to SPRO and I looked for the authorization object COM_PCAT in his Role,

and I found he has permission for all the activities, even Change and Delete,

Is there another place where I have to look for this permission ?

Please help, thank you !
