You use the Attributes Equality sub
tab on the Comparison Rule tab in the Comparison
Rules application to create attributes equality clauses.
Before you begin
These instructions are based on the assumption that you have
selected a comparison rule or created a rule in the Comparison Rules
application and are positioned on the
Comparison Rule tab.
Select an existing rule or create a rule using the Comparison Rules
application before you perform these steps.
About this task
An attributes equality clause identifies the specific attribute
or attributes of a child or parent object in
Data Set 1 to
compare with specific attribute or attributes of a child or parent
object in
Data Set 2 when a comparison rule
is processed.
Procedure
- On the Comparison Rule tab in the
Comparison Rules application, select the Attributes Equality sub
tab.
- To add an attributes equality clause, in the Attributes
Equality Clauses table window, click New Row. The application generates a sequence number for each new row
created. By default, the application creates sequence numbers in increments
of 10 in ascending order. You can modify the numbers as needed or
add new clauses with sequence numbers that fall between already-existing
numbers. Each sequence number must be unique. When you save the record,
the application sorts the clauses in ascending numeric order.
- Optional: If you are creating multiple clauses,
in the (... field (open parenthesis), enter
an open parenthesis.
- In the Data Set 1 Object field,
click Select Value and select a Data
Set 1 object.
- If you selected a specification (such as ASSETSPEC) for
the Data Set 1 Object field, in the Data
Set 1 Class Structure field, click Select Value and
specify a class structure. The selected class structure
populates the Data Set 1 Class Structure field.
The classification for the selected class structure is displayed in
the Data Set 1 Classification field. A description
is displayed in the Data Set 1 Class Structure Description field.
- In the Data Set 1 Attribute field,
click Select Value and select a Data
Set 1 attribute. The title of the Data
Set 1 attribute is displayed in the Data Set
1 Attribute Title field.
- In the Data Set 2 Object field,
click Select Value and select a Data
Set 2 object. The value selected populates the Data
Set 2 Object field.
- If you selected a specification (such as ACTCISPEC) in
the Data Set 2 Class Structure field, click Select
Value and select a class structure. The
selected class structure populates the Data Set 2 Class
Structure field. The classification for the selected class
structure is displayed in the Data Set 2 Classification field.
A description is displayed in the Data Set 2 Class Structure
Description field.
- In the Data Set 2 Attribute field,
click Select Value and select a Data
Set 2 attribute. The value selected
populates the Data Set 2 Attribute field, and
the title of the Data Set 2 attribute is displayed
in the Data Set 2 Attribute Title field.
- Optional: In the Data Set 2 Unit
of Measure Attribute field, click Select Value and
select a unit of measurement attribute. Use this option
if you want to compare attributes with a unit of measurement attribute.
For example, if you are trying to determine whether the amount of
RAM on a notebook in Data Set 1 matches the
amount of RAM on a notebook in Data Set 2,
you select RAMSIZE for an attribute. When you specify the parameters
for the Data Set 2 object in the comparison,
you can specify RAMUNIT as a unit of measurement attribute. The object
in Data Set 1 is successfully matched with
the Data Set 2 object only if the value and
measurement unit of the object in Data Set 1 is
equal to the value and measurement of Data Set 2 object.
1 GBYTE matches to 1 GBYTE; it does not match to 1GB. When
you select a value, it is displayed in the Data Set 2 Unit
of Measure Attribute field. The title of the unit of measure
is displayed in the Data Set 2 Attribute Unit of Measure
Title field.
- Optional: In the ...) field
(close parenthesis), enter a close parenthesis.
- If you are creating multiple clauses, in the Sequence
Operator field, click Select Value and
select the appropriate sequence operator. If you use multiple
clauses, specify a sequence operator for all rows except the row with
the highest sequence number. The row with the highest sequence number
cannot have a sequence operator.
- Optional: Repeat steps 2 through 12 to create
additional attributes equality clauses.
What to do next
When you have entered all attributes equality clauses, if
appropriate, you can create one or more filters for the comparison
rule by selecting another sub tab in the application. When you complete
all components of the comparison rule, save the comparison rule.
