Change Document Status

Hello,

I need some help for changing the document status in the following case.

We have a status net with different status and the last one is VOID without any following status.

The problem is now, that an administrator should have the possibility to change this status to a previous status if somebody made a mistake.

I've tried to change the status with CV02N and also with the BAPI's BAPI_DOCUMENT_SETSTATUS and BAPI_DOCUMENT_CHANGE2 but that doesn't work.

Does anyone know a solution for this problem?

Thanks for your help.
