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

You need to check the assignments from provider &V3& which is a source
provider of key figure &V2&. Unit field &V4& needs to be assigned to a
field of the target structure, and key figure &V2& has to use this
field.
Either unit field &V1& is not valid, or it is not connected to &V4&.

be set to "use system-wide unique name".
