Issue: Planned Orders having Plan end date as Due date

Hi All,

I need some pointers to understand the root cause of the issue (may be an observation).

I am able to see some Planned orders which are pegged to Safety Stock Demand having due date equal to plan end date. This is a Make part having phantoms. Longest Lead Time item (it has got no onhand) has 98 Days as LT. Including MFG, LT for FG is coming to 104 days. This is based on analysis.

We are using  Material constraint (ECC) plan only (resources are turned off for both scheduling and planning prespective). Plan is recommending a due date equal to Plan end date. When I saw the pegging I didnt find a clue why the recommendation is given like that. Plan has given a recommendation i.e an year from today.
