When creating a new invoice the following error message appears, and blocks the creation of the latter. "You do not have permission to read the table Responsibility Center.
what can be causing this and what shall i do to solve this error message?
First check your license and see if you have responsibility centres.
If you do then it is a permissions error for the user.
If you do not then I would guess your partner delivered a system they created with a license that was not yours and they populated the responsibility centre. Until this data is cleansed you cannot continue.
