Error message

How to fix this error?

The current version only allows for three currency. The first currency
is the local currency. The second currency is the integrated Controlling
currency. The remaining (additional) currency can be chosen by the
customer. In this case, however, there are two existing currencies that
need to be entered as the additional currency. This is not possible.
Contact SAP to see if there is a possiblitly to migrate anyway. For
example, one of the two currencies could be defined as the addtional
(third) currency.
