A

data pack

subset includes a part of the data in the original data pack. The subset is referentially intact and maintains primary and foreign key relationships. The criteria that you use depends on the data that you want in the subset.

For example, a CUST_DATA data pack contains customer data for customers in all global locations. Your test case requires data for customers in specific locations with a certain number of loyalty points. You can create a PRIV_CUST

data pack

that contains the required data from CUST_DATA.

Use row-level tags to tag the rows that you require in the

data pack

. You use row-level tags as criteria when you create the

data pack

subset.

The

data pack

that you create includes the data that you tag and its related data.

You can run a job to view the subset computation before you create a subset. View the subset computation to ensure that the subset criteria that you use returns the required data.
