Editing a data set alias

When you edit a data set alias, you need to be aware of how it is being used in relation to the data set it refers to. Some restrictions apply when the references data set is also open for editing.

When you open a data set or its alias for editing, if another alias or the referenced data set is already open, a message window opens indicating that the data set or alias cannot be opened for editing.

If a data set alias is added to a project and the project is taken offline, the alias and the referenced data set can be edited independently. When you take the project back online, you must reconcile any differences between the alias in your project and the referenced data set on the remote system.
