Overview
A new extended attribute type of Boolean has been added. Boolean attributes can be rolled up during formulation. The roll up behavior can be set on the attribute template.
The Basics
The Boolean attribute
displayed in consumption, with optional text:
Figure 1. Boolean attribute
A Boolean attribute
is created like any other extended attribute.
Once on the extended attribute template in ADMN, select Boolean as the
attribute type. Once Boolean is selected
the following fields are available:
Figure 2. Extended attribute template
Display Text
– This is the text that is displayed next to the dropdown in consumption. This field is optional. When left blank, only the dropdown will be
displayed in consumption.
Default State
– This is the value the dropdown is set to when the attribute is added to the
specification. There are 3 states for
the Boolean attribute: True, False and
Null.
Rollup Behavior –
This field defines the rollup behavior of the attribute during
formulation. There are two options,
Rollup as True if all items are true and rollup as true if one item is
true. See the following rollup examples:
Rollup as True if all are True
The following inputs
are added to a formulation specification “Lemonade”:
|
Input |
|
|
Sugar |
Organic = True |
|
Water |
Organic = True |
|
Lemon Juice |
Organic = False |
In the previous table, the lemonade produced by the formulation specification
would include the extended attribute/value pair of Organic = False. This happened because the Lemon Juice input
was not organic. If all inputs were
marked as true the output’s extended attribute would be Organic = True.
Rollup as True if one is True
The following inputs
are added to a formulation specification “Lemonade”:
|
input |
|
|
Sugar |
Genetically
Modified = False |
|
Water |
Genetically
Modified = False |
|
Lemon Juice |
Genetically
Modified = True |
In the previous
table, the lemonade produced by the formulation specification would include the
extended attribute/value pair of Genetically Modified = True. This happened because the Lemon Juice input
was genetically modified. If all inputs
were marked as true the output’s extended attribute would be Genetically
Modified = False.
Allowing Nulls
Null values are
either ignored during rollup as if they did not exist in the set or stop the
rollup action. This will all depend on
if you select “Allow Nulls” or “Do Not Allow Nulls” inside the extended
attribute listing on the output popup.
Figure 3. Null values
Note: An extended
attribute is considered Null if the attribute does not exist on the input or if
the attribute does exist and no value is set.
For example, if you
have “allow null” selected in the following example, the result would still be True. However if you
selected do NOT allow null then nothing would appear in the “Theoreticals”
column:
|
input |
|
|
Sugar |
Genetically
Modified = False |
|
Water |
Genetically
Modified = BLANK (OR the Genetically Modified EA doesn’t exist) |
|
Lemon Juice |
Genetically
Modified = True |
Printing and Searching
Boolean attributes
can be searched and printed and are available everywhere other extended
attributes are supported.
Calculated Extended Attribute
Boolean attributes can be referenced by calculated extended attributes. An integer that represents the selected value will be returned: 0 is false, 1 is true, -1 if not set.
