rescheduling query

Hello Gurus,

I have a scenario where after rescheduling the quantity is not being given to the order with lower delivery priority even though stock exists.

Order A with delivery priority 1 Ordered qty 50 ICS confirmed qty before rescheduling 10 ICS

Order B with delivery priority 2 Ordered qty 50 ICS confirmed qty before rescheduling 30 ICS

There is total of 70 ICS available.

I would expect that after rescheduling Order A should get 50 ICS and order B should get 20 ICS.

But instead order A is getting 50 ICS and Order B is getting 0 confirmed. When i do a manual availability check for order B then 20 ICS does get confirmed - then why is it being ignored during rescheduling?

Am i missing something here??

Please let me know

Thanks
