ASCP is creating Planned Order earlier even if no capacity Available for resource

We are using ATP based on ECC Plan Output and for some of the item we are observing, when the Planned Order is suggested to create IR it does not consider the cumulative capacity available and gives a sooner date which is not possible for manufacturing organization to build the unit.

What we observe is when Planned order is suggested, it is base on net capacity available for resource however ATP inquiry work based on Cumulative capacity available for recourse. ATP inquiry works correctly.

We tried multiple profile however in case of Planned Order against safety stock ASCP is not honoring cumulative capacity for resource.
