In addition to reviewing the document, Bharat linked to, note the item number that isn't visible and also one that is, and go to the Inventory module. In the Organization Items form, query for the item that does NOT appear, in the organization linked to your AR module. On the Inventory tab, is it transactable? On the Order Management tab, are Customer Ordered, Customer Orders Enabled, Shippable, and OE Transactable enabled? On the Invoicing tab, are the Invoiceable Item and Invoice Enabled boxes checked? Note the values, then query the item that is visible, and compare the settings. If they are different, chances are that is why the one item appears and the other doesn't. Coordinate with your inventory team as appropriate in your business before making changes.
