About Presentation Tables
Subject areas contain presentation tables, and presentation tables contain presentation columns and presentation hierarchies. Presentation tables function as intuitive categories that collocate the columns and data users need to create visualizations and analyses.
In most cases, you create presentation tables by dragging and dropping logical tables from the logical layer into a presentation layer's subject area. The names and object properties of the presentation tables are independent of the logical table properties.
In most cases, a presentation table contains columns from its corresponding logical table. But you can build a presentation table containing columns from a different logical table within the same business model. In such cases, be aware that building a presentation table in this way can cause query errors when a user selects these columns.
