Add an Action Block

You can add action blocks to Structure Charts or Action Block Usage diagrams. The parent can be an action block, a process, or a Procedure Step.

After you add an action block, you cannot delete it using the Structure Chart or Action Block Usage tool.

The following criteria are used for an action block to be on the delete list:

• Not protected
• Not used by another action block (No REFDBY association)

If the action block is associated with an elementary process (DTLOGT association), you must use Analysis—Activity Hierarchy to delete the action block and its associated processes.
