Data task automation (DTA) in Microsoft Dynamics 365 for Finance and Operations lets you easily repeat many types of data tasks, and then validate the outcome of each task.
Data task automation is very useful for projects in the implementation phase, in order to automate the creation and configuration of data projects.
We can configure and trigger the execution of import/export operations, such as the setup of demo data and golden configuration data, and other tasks that are related to data migration.
It can also create automated testing of data entities by using task outcome validation.
