Suppose I filter numerical attributes only for applying some functions using AttributeFilter operator.Can i select the nominal attributes from my data after completion of the function without using examplesourse operator.
Hi, that's one possibility, but in some cases this effort isn't needed: If you only want to have an attribute subset temporarily, you could use the AttributeSubsetPreprocessing Operator. It will deliver the subset to the inner operators and re-add the other operators to the resulting example set.

Look into the IOObjects, using which you can store your example set, and then repeatedly butcher and resurrect it, as in the following....
