How To Find EBS Column Value Descriptions?

How do I find the name of a column value in a EBS table?

A simple example is:

In Inventory under the tab General Planning, the field 'Make or Buy' might have displayed 'Make'.  But the column in the table from the form has a numeric value, say, of, '1', i.e. :   select planning_make_buy_code from mtl_system_items_fvl

How do I find the description 'Make' that is cross-referenced to the code '1'?

With Appreciation.
