To re-create a collection, perform the following steps: 1. Pull down the Maintenance menu. 2. Choose the Recreate... menu item. If you change a test description or the contents of a group after including it in a collection, you must re-create the collection to include the changes. CAUTION Before recreating a collection, be sure that the prologue and epilogue files associated with the collection and template, prologue, and epilogue files associated with the tests in the collection exist in their proper directories. If DTM cannot find the template, prologue, or epilogue files specified in the original CREATE TEST_DESCRIPTION command, the original collection is deleted but a new collection is not created.
