PSA load

Hi all,

Can you let me know regarding the following issues?

1) Do I have to delete data if I reload data with 'FULL load' option because someone already did 'initial load' and 'delta load'?

2) I enhanced 4 CHARs to my 2LIS extractor, do I have to reload with 'initial load + deltal load' OR ' full load' to catch the values for those new fields?

Thanks

J.
