PROJECT_STEP 
Logical Entity Name  PROJECT_STEP 
Default Table Name  PROJECT_STEP 
Physical Only  NO 
Do Not Generate  False 
Owner  BARD_CAP_PROD 
Definition  
The annotations (context items) for a step show the annotations of the incoming arrowhead on the edge between the experiments and the "follows" experiment.  Thus the annotations can refer to the experiment or the step (aka decision) that instigated the experiment.  Bear in mind that the "follows" experiment can be null, i.e. this the experiment does not have a predecessor.  Primary screens tend to have this characteristic.
