PROE Integration title block

Hi,

I'm trying to update the title block of the drawing in PROE with the Revision field after release of the DIR. The problem I'm facing is that the document cannot be checked out post release and hence I'm unable to update revision field in the Title block of the drawing.

Also the "Update Parameters" in .Reiss doesn't have "Update Revision" Option. Please let me know how I can achieve this.

Thanks in advance
