While you work on multiple mappings in a complex scenario, situations might demand that you put multiple data flows in a single mapping in order to justify the performance and the complexity. A sample mapping depicting the preceding statement is shown in the following screenshot:

If you execute the mapping, the session might fail because of the primary key and foreign key violation. As the Employee and Department tables have dependencies on each other, when you run the mapping containing both the flows, the process might fail if the data violates the dependency.

To avoid the issue, Informatica PowerCenter contains a utility called the target load plan—how do you plan to load the data into multiple targets in a mapping? We can load the data in a particular sequence in multiple targets in a mapping in order to avoid failure due to constraints.

Consider that the EMPLOYEES table data depends on the DEPARTEMNTS data because of the primary key and foreign...
