Hi,

I would like to know different possible ways in appending extra values like new uniqueidentifiers, sequence numbers, random number. Can you please tell what type of data flow components helps us ?

Append what to where? Do you want to add new columns with such vaues to a path within the data flow task?

Derived Column Transform?

Script Transform?

Row Number Transform ? (http://www.sqlis.com/default.aspx?77)

If i use Derived Column Transformation, how can i generate uniqueidentifiers and sequence numbers for each row?

For GUIDs you would need to use the script task, as there is no "New Guid" function in the expression syntax.

For sequence numbers or row numbers I assume, then again the script task is required. For an easier life you can use the cunningly named Row Number Transform I mentioned previously, which does just that, and comes as a simple MSI to install.
