Hi Victor,
In my opinion, if you miss some required authorizations, you can check them out in SU53.
I remember I face the same kind of error last year within SFIN.
Please check if the note https://launchpad.support.sap.com/#/notes/2029333 helps or not.
To prevent delays of problem fixing, you'd better to open an incident to component CA-FE-FLP-EU 
. Wait for your solution.
Regards,
Ning
