Creating a new task with overridable parameters
Couple of days ago I saw a question on one of the newsgroups regarding creating a task where the operator can specify one or more parameters that are used by the task when launching the task. Unfortunately it’s not possible to create such as task today in the OpsMgr console, however you can do this using the SP1 RC authoring console or just in XML. The key part is defining a new WriteAction and specifying which parameter can be overriden (see the highlighted section below). Here is a sample MP that shows how you can do this in XML:
