Supply Eligible: When there is no sufficient quantity available.

Example: When user tries to book a sales order for Item ‘TestItem’ for a quantity of 10 but the item contains zero quantity. Then the Sales Order Line Status change to ‘Supply Eligible’.

Supply Partial: When the quantity is partially available.

Example: When user tries to book a sales order for Item ‘TestItem’ for a quantity of 10 but the item contains only 4 quantities. Then the Sales Order Line Status changes to ‘Supply Partial’.
