A variant from another transaction (&2) was selected

What causes this issue?

The report PPIO_ENTRY is used by different transactions. The scope of
functions of the individual transactions is controlled via the variant.
In the variant you define the transaction to which it belongs. For
technical reasons it is not possible to display only those variants that
belong to transaction &V1& when the user is selecting a variant.
Therefore, the system can only check whether the user has chosen a
suitable variant after the selection has been made.
You are working in transaction &V1& of the information system or mass
processing and have selected variant &V3& of transaction &V2&.

System Response

The system carries out an authorization check for transaction &V2& which
is defined in variant &V3&. If an (old) variant that does not contain a
transaction is loaded, the system checks whether the user has
authorization for transaction COHV:
If you do <ZH>not</> have authorization for transaction &V2& the system
issues this message as an error message and terminates the transaction.
If you have authorization for transaction &V2& the system issues this
message as a default as a information message; you can also define the
message category yourself. This prevents the system from loading a
variant of another transaction.
You can use transaction <DS:TRAN.SE38>SE38</> to define for which
transaction the system carries out an authorization check for variant
&V3& of report PPIO_ENTRY.
You can define the category of the message that is issued by the system
when the user chooses a variant of another transaction in the
Customizing activity <DS:TRAN.OPJB>OPJB</>. You can choose from the
following settings:
SPACE: The system does not issue a message and loads the selected
variant, provided that the user has authorization for the transaction
maintained in the variant.
S: The system loads the variants and issues a success message, provided
that the user has authorization for the transaction maintained in the
variant (default setting).
E: The system terminates the transaction when the user tries to load a
variant from another transaction.
