In cognos 'group' is used to suppress the duplicate values And 'associate' is used to suppress the values if it is one-one relationship.

Group - It Eliminates the Duplicate values from the report break the columns. Its having a one to many relationship.

Association-It Eliminates the Duplicate values from the report and its having one-one relationship.

Both Group & Association eliminate duplicates in a column.But we cannot use Association alone.It should have one to one relationship with grouped column. Using Association is a performance enhancement technique.
