Scenario – Counting Objects 
A break in the data pattern can be recognized when the count of a certain object 
reaches a specific value. You have a set of four contact records that need to be 
mapped to a single record. 
As shown in the illustration, the AddressFile data source contains multiple 
ContactSets. Each ContactSet contains four Contacts. 
The CompanyFile data target contains multiple Records. Within each Record, 
there are four Company fields. You want to map the Company field of one 
Contact in the ContactSet to one of the Company fields in Record. 
Define a specific number of data objects as a single data object. Use the Type 
Designer to define the address file in terms of ContactSets, and use a component 
rule on the Contact component of ContactSet. Define the company file of 
records. 
Use the Map Designer to create a map that maps the AddressFile to the 
CompanyFile. Create a functional map to map a single ContactSet to a single 
Record. 
Defining a specific number of data objects as a single data object enables each set 
of four contacts to be recognized as a single data object. This allows you to map 
each set of four contacts to a single record in the output.
