Some banks need the consumer data if that type of lending exceeds their small business lending. Everyone is different.
Review the guide to data collection and FAQs at the FFIEC site. Also, pay close attention to the loans that are reported - they tie directly to call report/TFR line items, so check your bank's call report process and become familiar with the call report line items and definitions (such as loans secured by real estate, and "primarily") in the call report glossary.http://www.ffiec.gov/cra/default.htm
Small business loans are drawn from line items 1e1, 1e2,4 (4a for assets >300 million)
Small farm are drawn from lines 1b and 3.
The call report instructions explain what goes into each of those lines. Your reporting population will be loans in the category originated/renewed/refinanced/modifed in your reporting time period that meet the size requirements (up to and including $1million for small business; up to and including $500,000 for small farm).
