Order called before TECO of the previous - strategy plan

Dear all,

I have a strategy maintenance plan with following parameters:

Tolerance (both - and +): 0

Shift factor (both late and early): 0%

Call horizon :95%

Completion Requirement: Yes

Scheduling indicator: Time

We are using background scheduling and we set the job to work once a week.

However, for the strategy plan, despite completion requirement, the next order is called every time the scheduling runs, although the previous call is not TECO. Up to now, there are ten orders that are scheduled despite the fact that the preceding call was not completed.

Could you please help me understand and solve the issue?

Thanks in advance,
