InterfaceLink2 is used for third-party implementations only.

Note that this differs from just "InterfaceLink" ("1").

For newer Menu Setup UI, Build 1730 and above, InterfaceLink1 is entered into the Advanced Setup tab.

How to make a Menu Item an Inventory Item

A Large Pizza would not normally be an inventory item, but 1 Large Dough would be.

To indicate that this is an inventory item, in the interfaceLink2 have
- INVENTORY_ITEM:UNITTYPE:UNITS/UNITTYPE
- ie, tomatoes by case, and 20 Units / case
- INVENTORY_ITEM:Tin:12
A separator of <> will be used to separate interfaceLink tokens.
- TODO JOE write an interface link parser.

How to Specify a Recipe for the menu item

A Large Pizza is made of Dough, cheese, tomato sauce and toppings.

To define the the recipe we will use interfaceLink2
We would need to indicate that the Pizza has a recipe is made of 1 Large Dough
With the modifiers (cheese, toppings), we need to indicate how much is used which depends on what it's ordered with.
1 Large Pizza would use more cheese then 1 Small Pizza.

Defining Menu Item RECIPE

Defining Menu Item Option RECIPE

RECIPE:TYPE<USER DEFINED>-<PLU>,<units>;<PLU>,<Units>|TYPE <USER DEFINED>-<PLU>,<units>;<PLU>,<units>
Example RECIPE:LARGE-111000,10;111001,11|MEDIUM-111000,20;111001,15
Example 2:
- For pepperoni, RECIPE:DEFAULT-2222,5|LARGE-2222,10|MEDIUM-2222,5|SMALL-2222,3 for pepperoni
- When ordered with a item that has TYPE=LARGE, deduct PLU 2222 10U from inventory
- When ordered with a item that has TYPE=MEDIUM, deduct PLU 2222 5U from inventory
- When ordered with a item that has TYPE=SMALL, deduct PLU 2222 3U from inventory
- When ordered with a item that has TYPE=DEFAULT (when not specified), deduct PLU 2222 5U from inventory (DEFAULT)
- 2 Tokens (RECIPE) : (LARGE-PLU,units;PLU,units;PLU,units|MEDIUM-PLU,units;PLU,units)
- 2nd Token has Repeating Tokens (LARGE-PLU,units;PLU,units;PLU,units)|(MEDIUM-PLU,units;PLU,units)
- The inside Tokens have 2 Tokens (LARGE)-(PLU,units;PLU,units;PLU,units)
