I agree with the analysis of Peter and I think transaction is already assigned to role Finance Manager. The topic came up because c.wimonrat is no longer holding the Finance Manager role (removed during SAP role review process 2016 as this manager role is limited to the manager and its deputy), but he is in charge to maintain the exchange rates for TH10.
The question is: Does it make sense to further spread the right to use the transaction to all Controllers?
I would say no.
TH10 has to organize finance tasks in a different way.
Kind regards, Frédéric
