Improve the output for the validation module

[mkao006]

Currently it just returns an error, however, this is not very helpful.

We should have the following:

• Return validation flag for current run
• Return invalid flag for scheduled run.

Now an optional arguement getInvalidData is available and returns in the invalid data if TRUE
