the unit that the recipe can acquire first. The acquired unit must
belong to the unit class of the unit procedure step. Recipes can
configure upstream and/or downstream dependencies defining a

acquired unit supports the flow path to other units.
formula
A category of recipe information that includes process inputs, process
parameters and process outputs.
formula value
A value that is assigned to a parameter defined for a specific step of a
phase, operation or unit procedure. A formula value may have a literal
value assigned to it or it may receive a value from the next higher
recipe level when the batch is run.
global binding requirement
A Global Binding Requirement is defined within the Equipment Editor
for an area model, and is automatically applied to every unit
requirement within a recipe. This saves the effort of having to
manually add the binding requirement to every unit requirement in
every recipe.
global unit attribute
A Global Unit Attribute is a unit attribute that has been configured to
be automatically applied to all unit classes defined within the area
model. This saves the area model author the effort of having to
manually assign the unit attribute to every unit class.
header
General information about the recipe that includes the procedure
