Attributes Equality Clauses

An attributes equality definition is a component of a comparison rule defined in the Comparison Rules (SP) application. You use the Attributes Equality subtab on the Comparison Rule tab in the application to create attributes equality clauses that define how to compare the specific attribute or attributes of a child or parent object in Data Set 1 with specific attribute or attributes of a child or parent object in Data Set 2 when the system processes a comparison rule.

The following table describes the elements of an attributes equality clause:

 

Field

Function

Rules/Requirements

Sequence

Number that specifies the order in which to process the clause.

Mandatory.

Use a unique number for each clause.

Use a number greater than 0.

Open Parenthesis  ( ...

Marks the beginning of an expression. Parenthesis marks group expressions to control the order of operations when you use multiple clauses joined by a logical operator (AND or OR).

Optional. However, for each open parenthesis, use a corresponding close parenthesis.

Data Set 1 Object

Specifies the Data Set 1 object for reconciliation.

Mandatory.

Selected from a value list that includes the following values:

For assets:

  • ASSET (Asset)

  • ASSETSPEC (Asset Specification)

  • ITEM (Item)

  • ITEMSPEC (Item Specification)

For configuration items (CIs) :

  • CI (Configuration Item)

  • CISPEC (CI Specification)

Data Set 1 Class Structure

When you select a specification as the Data Set 1 object, this field identifies a specific class structure for the object in the attributes equality clause.

Mandatory if you select a specification for the Data Set 1 object.

Selected from a value list. Values in the list are class structure identifiers for the objects that belong to the top-level Data Set 1 objects.

Data Set 1 Class Structure Description

Displays a description of the selected class structure.

Read-only field.

Data Set 1 Classification

Displays the classification for the selected class structure.

Read-only field.

Data Set 1 Attribute

Identifies the specific attribute of the Data Set 1 object or class structure to use for the Data Set 1 object in the attributes equality clause.

Mandatory.

Selected from a value list. The Data Set 1 object selected determines which values the system displays in the value list.

Data Set 1 Attribute Title

Displays the title of the Data Set 1 attribute selected.

Read-only field.

Operator

Identifies the operator for the reconciliation.

Mandatory. The equals (=) operator is read-only; it cannot be changed.

Data Set 2 Object

Specifies the Data Set 2 object for reconciliation.

Mandatory.

Selected from a value list.

Data Set 2 Class Structure

When you select a specification for the Data Set 2 object, this field identifies a specific class structure for the Data Set 2 object in the attributes equality clause.

Mandatory if you select ACTCISPEC for the Data Set 2 object.

Selected from a value list. Values in the list are class structure identifiers for the objects that belong to the top-level Data Set 2 objects.

Data Set 2 Class Structure Description

Displays a description of the selected class structure.

Read-only field.

Data Set 2 Classification

Displays the classification for the selected class structure.

Read-only field.

Data Set 2 Attribute

Identifies the specific attribute of the Data Set 2 object to reconcile.

Mandatory.

Selected from a value list. The Data Set 2 object selected determines which values the system displays in the value list.

Data Set 2 Attribute Title

Displays the title of the Data Set 2 attribute selected.

Read-only field.

Data Set 2 Unit of Measure Attribute

Identifies the unit of measurement attribute when the attribute selected requires a unit of measurement, such as megabytes or kilobytes.

Optional.

Available only when creating a rule where the Data Set 1 object is ASSETSPEC and the Data Set  2 object is DEPLOYEDASSET.

Data Set 2 Unit of Measure Attribute Title

Displays the title of the Data Set 2 unit of measure attribute.

Read-only field.

Close Parenthesis ... )

Marks the end of an expression. Parenthesis marks group expressions to control the order of operations when you use multiple clauses joined by a logical operator (AND or OR).

Optional. However, for each close parenthesis, use a corresponding open parenthesis.

Sequence Operator

When more than one clause exists, this operator prescribes how the current clause relates to the next clause in the sequence.

Required if more than one clause exists.

Must be empty for the last row in the sequence (that is, the row with the highest sequence number).

Selected from a value list that includes the following values:

  • AND

  • OR
