Import data from SharePoint list to Collection

[Kevin_Maxwell]

I have a Collection called "Beneficiary_Collection" which it has the following columns:

• First_Name
• Last_Name
• Date_of_Birth
• Gender

I have a SharePoint list called "Beneficiary" which it has the above mentioned columns as well as other columns. I need to map each column and import the data/rows from SP (Beneficiary) list to Collection (Beneficiary_Collection). I have tried Collect with ShowColumns function. It does create new columns instead of adding to the existing columns. Is there any way to map columns?

Thanks,

Kevin
