I have found to test disposal on any record I must have 2 records tag inorder to have the disposal menu item available. Is there another way to just demostrate disposal against a single record?
From my testing, you only see this when Advanced Disposal Processing is selected in System Options>Features. Disposal is supposed to go through Consignments with this feature enabled. If you're not using Consignments, switch off that Advanced feature and it should behave as expected.
