This field contains the ID of the POS data table that is behind the order list grid of the Hospitality Startup POS for a KOT List layout view.
The data table is a view of the POS Transaction table. The default list shows KOTs but if you press the hospitality type button again (or a button with the HOSP-SWITCH-TYPE command and parameter SAMETYPE) you see the unpaid orders for the hospitality type. You toggle between those two lists.
When you select a Layout View option, the system automatically enters the default data table for that layout view in this field.
