Hello Jeff,
Unfortunately I left the organization where I was trying to implement this scenarion long time back.
About reply of Mallikarjuna, I heard from my colleague in that organization that it did not work.
However, I remember that 'CRM_SVY_VALUES_READ' contained complete survey data, but in XML format.
Maybe you could try ABAP XML parsing APIs to parse this XML & retrieve the data.
Wish you all the best.
Warm regards,
Amey Mogare
