Add a New Link Rule ClauseAdd a New Link Rule ClauseYou use the Link Rule tab in the Link Rules (SP) application to add new link rule clauses to a link rule.
When you save a modified link clause, the system evaluates the link rule to determine whether the clauses are valid expressions; if a clause is not valid, the system displays an error message and does not save the link rule.
For more information about the components of a link clause, see Link Clauses.
For more information about link rule requirements, see Link Rule Requirements.
On the List tab in the Link Rules (SP) application, click a row to select the link rule that you want to change. The system displays the selected link rule on the Link Rule tab.
In the Link Clauses table window, click New Row. The Row Details open.
In the Sequence field, if appropriate, enter a sequence number to specify the order in which to process this clause.
Note: The system generates a sequence number for each new row created. By default, the system creates sequence numbers in increments of ten in ascending order. You can modify the numbers as needed or add new clauses with sequence numbers that fall between already-existing numbers. When you save the record, the system sorts the clauses in ascending numerical order.
If appropriate, in the (... field (open parenthesis), enter an open parenthesis.

the asset attribute in the Data Set 2
Attribute Title field.
