Authorization to access an order

Dear All,

for some users I would like to display an purchase order (Transaction ME23N)only if it is from a specific vendor. For example the user should only have access to this order if it is from vendor XYZ. If it is not from this vendor then the user has no rights to look at this order.

Any suggestions how I can realize this?

Thanks a lot.
