Creating attributes equality clauses

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

  1. On the Comparison Rule tab in the Comparison Rules application, select the Attributes Equality sub tab.
  2. 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.
  3. Optional: If you are creating multiple clauses, in the (... field (open parenthesis), enter an open parenthesis.
  4. In the Data Set 1 Object field, click Select Value and select a Data Set 1 object.
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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.
  10. 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.
  11. Optional: In the ...) field (close parenthesis), enter a close parenthesis.
  12. 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.
  13. 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.
