SAP Error Message - Details

• Message type: E = Error

• Message class: UO - Maintain Currency Tables TCUR* for Euro Introduction

• Message number: 120

• Message text: Exch.rate type &2 is the rerouting target for another exch.rate type

What causes this issue?

You are already using exchange rate type &v2& as the rerouting target
for exchange rate type &v3&. If you reroute the conversion into
external currencies for two exchange rate types to the same target
exchange rate type, you can no longer distinguish the original exchange
rate types (as of the rerouting date).

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

&WHAT_TO_DO& Enter a new exchange rate type for each exchange rate type
by which you want to convert amounts into external currencies (via the
euro as base currency). In each case, use an exchange rate type that
you have not used before.
