After modifying a mapping used in configuration tasks, what are the methods to deploy the changes?

The correct approach to deploying changes after modifying a mapping used in configuration tasks is to save the updates to the mapping within the configuration tasks. This directly ensures that the changes made to the mapping are applied and reflected in the tasks that rely on it.

When you make changes to a mapping, it's vital to save these updates so that any configuration tasks referencing the mapping will utilize the latest version. This process effectively integrates your alterations into the existing workflow without needing to re-import or manually adjust the configuration tasks, which can potentially introduce errors or misalignments.

While options such as saving as a new mapping or notifying users about the changes can be important in particular contexts—such as change management or version control practices—they do not directly deploy the changes within the existing configuration. Importing a new mapping from PowerCenter can be redundant if the changes are already encapsulated in the existing mapping that you're modifying. Therefore, saving the updates is the most direct and appropriate method to ensure that the configuration tasks operate with the most current data definitions.
