EXCHANGE RATE TYPE in SAP in OB08 (Foreign currency revaluation issue)

Dear Viewers, Problem: I recently added company codes for swizz, Germany and others. I had to define the exchange rate types in OB08(directly in QAS as this is non transportable), I got a green message saying that "You dont have maintainance authorization" SOLUTION: In order to have exchange rate type to be saved, we have to define the translation ratios in the following config: SPRO-->SAP NETWEAVER-->gen settings-->currencies-->define translation ratio. I defined 1:1 in my case and it worked.
