A very simple thing to check before applying some of the good suggestions above is make sure your setup table is populated (because this is an LO extractor). If you have questions on that - many posts of LO data extraction.
If you don't have setup table populated and you try to run RSA3 (Full update mode) - then of course you will not get any data.
Can you clarify whether you are getting any data at all - or is it just your enhancement fields not being populated when you test in RSA3....?
