Block Replacement

With block replacement a data row marked with a dash indicates a data block that consists of that row and all data that is nested underneath it. Each such block replaces the corresponding data in the policy database.

Other blocks for the same policy item remain unchanged. A data block where you have edited all the fields to blank would delete all the corresponding data from the policy database. For example, the following would delete the reply definitions from a message: 
Action                   - REPLY
        Pass/Selection         : 
        Retry Count            : 
        Reply Text             :
You can also specify just the block header line to delete all the data in that block. Thus, the equivalent for previous example would be: 
Action                   - REPLY

You can also delete data by specifying:

Message ID : ABC123I

or

Minor Resource Name : aMinResName

If no related detail lines follow, then all related details are deleted. In this case, all actions for message ABC123I as well as the message description will be deleted, but the message ID will not be deleted. Correspondingly, all definitions made for a minor resource will be deleted, but the minor resource itself will not be deleted.
