Status management in WF

Hi,

issue:

there is a WF which triggers for ECM

Flow is as follows:

Step-1 reached Approve or Reject

User Rejected, background task makes the ECM to Status=70 (which means rejected)

Step-1 again arrives, now user Approves.

Background task completes the step where FM "Status_change_Extern" is run and finally WF completes.

But when we check the ECM in CC03, it still shows Status=70, ideally it should have been 80.

So I feel is it to do with Status Management, which is not updating the ECM to 80.
