&4 Enter a unique identification

What causes this issue?

The identification you entered is not unique. The identification of a
scenario normally needs only to be unique within the scenario set. In
order to synchronize the scenario data with the SAP NetWeaver Business
Intelligence (SAP BI) system for reporting, the system generates a
unique identification for the combined identification of the scenario
set and the scenario. This unique identification can contain only the
characters "A-Z", "0-9", and "_" (underscore). When the system generates
the identification, it replaces any characters that are not allowed with
an underscore. In some cases, therefore, an ambiguous identification is
generated, for example "WKS-01" and "WKS/01" are both transcribed to
"WKS_01".
In this case, the scenario set that contains the ambiguous
identification is &V2&.
The identification generated for your scenario is &V1&.
