See About workflow inheritance for general information about inheriting maps and other properties from a base workflow.
To create a workflow definition that inherits maps and other items defined in another workflow definition, you select a previously defined workflow definition as the base workflow.
In Base Workflow, click Modify.
TIP The list contains only workflow definitions that have been transferred to Process Engine in this isolated region.
Note that the main map of the base workflow definition is overwritten by the main map of the current workflow definition. Submaps that are present in the base workflow definition are read only in the current workflow definition.
