Regarding the change status of leave workflow.

Question

hi friends,
i have copied the standard leave worklfow "WS12300111" and customized it just to meet our requirement means for multiple approvers.
everything is working fine in production  means if user ID "AIHR01' raise a leave request the workitem will go to "AIHR02" after his approving the workitem will go to the final approver means "AIHR03" after his approval the leave request will be completed and the status in the TC - PTARQ is coming as "APPROVED" means only after the approving of "AIHR03" the status is coming "APPROVED" but in some cases when user id "AIHR02" is approved instead of coming status "SENT" it is coming "APPROVED"  in TC-PTARQ and because of this status the workitem is coming blank in UWL of "AIHR03".
I have already incorporated the given below method in the "WORKFLOW" just to change the status from "APPROVED"  to "SENT" after the approval of user ID "AIHR02" but in some cases it is not working fine it is giving BUG.
begin_method changestatus changing container.

Request you to plesase help me to solve this issue .why in some cases instead of coming status "SENT" it is coming "APPROVED"  after the approval of user id "AIHR02".
BECAUSE of the  "APPROVED" staus the same workitem is coming blank in the UWL OF "AIHR03".
