Availibity date different from Order End date[SNP optimizer]

Hi All,

I need help with understanding the date being calculated here by system. After planning, system created SNP Planned Order with Availability date and 04/07/2016, but the End date for the Planned Order is 30/06/2016.

What could be the possible entities that might be influencing this deference in dates.

Please see the attached screens.

Regards,

Avinash
