SAP Message R7511 - An active version but not a revised one exists for InfoObject &1

Diagnosis
InfoObject &V1& should have been deleted via a transport. This was notpossible since the active version of the InfoObject was still beingused (for example, in InfoCubes or other InfoObjects).
Therefore, when importing the transport, only the revised version wasdeleted, and not the active version.

System Response
InfoObject &V1& is inconsistent and cannot be edited.

Procedure
Reorganize the InfoObject - tables (transaction RSD1 --> Extras -->InfoObject - Reorganize tables). In this way, the active version iscopied into the revised version, and InfoObject &V1& can be edited onceagain.
Note that InfoObject &V1& was intended for deletion. It was only notcompletely deleted due to references. If possible (meaning theInfoObject is no longer required), you should remove the references andthen manually delete InfoObject &V1&.
