SRM status Awaiting approval even if the Workflow finished correctly

Workflow is finished but document is not released, it stays on status "Awaiting approval".

we checked the notes 2127407, 1466930 & 1697416.

the blog https://wiki.scn.sap.com/wiki/display/SRM/Problems+with+%27Awaiting+approval%27+status

we checked the events, its fine.

So, we cannot fix the issue. and we cannt recreate.

Really we will be very grateful if some body know how to fix this issue.

thanks in advanced.
