BUS2038 terminating event to use when PM Order is created.

Hi

I'm a dummies for WKF management.

I need to create a very simple wkf.

When a 'A3' type of  PM notification is created the workflow is triggered using BUS2038.

I need to loop till to Desired_end_date (VIQMEL-LTRMN) is filled.

Using EDIT syncronous event the Workitem loop 1 time more then necessary, and using the EDITSYNCRONOUS event I don't know exactly what kind of termination event to use.

How to solve this issue ??

thanks  a lot for your help.
