Material Available Date not respecting supplier Promise Date when it exceeds LT

Hi,

I'm Running ECC  plan  with Supplier Capacity Constraints and Enforce Purchasing Lead-time Constraints   options checked.

Sometimes the Promise Date provided by our suppliers exceeds the Lead Time and ASCP generates Reschedule In recommendation. When ASCP calculates Material Available Date for SO, it assumes that better delivery date can be obtained.

Is there any way to enforce ASCP to respect the date promised by supplier even if it exceeds the agreed Lead Time?

Regards
