Problem in Events (Create and Change)

Hi all,

I have developed a worlflow for transaction FV50. Now the problem is that when i create a parking document a mali is sent to approver for approval.

Now suppose if approver doesn't do any action on the workitem which he had in his inbox and initiator changes the same document then the previous mail has to be removed and new mail has to be present in the approver inbox.

I tried using fork with two branches.

In one branch i kept entire flow and in one branch i have created a WAIT for event. It worked i.e. when i create a doc approver is receiving mail..but when i change the same doc then old mail is deleting from his inbox but he is not getting new mail for the changes he made for the document.

So please help me how to achieve the same.

Regards,

Sagar.
