How to fix this error?

Use Query Designer to change the query. The system provides a repair
proposal for the query if the variable is missing.
If the variable exists and is being used incorrectly, find out whether
or not the variable is used in the correct context.
The incorrect variable has variable type &V3&. You can use the following
variable types in the following contexts:
Characteristic value variables can be used to restrict (filter)
characteristics to values (master data). In other words, in the same
places where you can also use constant characteristic values.
Hierarchy node variables can be used to restrict (filter)
characteristics on hierarchy nodes. In other words, in the same places
where you can also use constant hierarchy nodes.
Text variables can be used in the query headers and can be used by
structure elements.
Formula variables can be used in all cases. Note: Formula variables can
have units but do not need to. Incorrect use can also arise here since
the system always calculates in accordance with the units. Formula
variables can also be used to create the upper and lower limits in
exceptions.
Hierarchy variables can be used to determine presentation and selection
hierarchies. In other words, in the same places where you can also use
constant hierarchy names.
Try to find the incorrect variables in the query and find out why they
are being used incorrectly.
You can delete the query if you do not need it any more.

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