item ON hand Qty is not visible at Line Level as showing NO retrieved data in sales order

Summary:

Hello,

I am trying to fetch the Item On hand in the sales order line, but I am not able to see the item on-hand details. If I created the ATP and assignment set based on organization only.

Our requirement is to get the item on hand on line level by keeping ATP, sourcing, and assignment set as organization level.

Assignment set with organization level and item level, but organization level not working.

ATP Rule

This rule is working but if i select the Organization then that rule will not work.

Anyone having any idea please do help me to solve the issue as its very urgent.
