bcp importing data from fewer fields to more table columns

Hello, please help me with this urgent problem,

I am trying to migrate data from one database to another using the bcp utility. Nowhere in the net I was able to find documentation on how to perform data importation when the destination table has more columns than the fields in my data file. I have a origin table which has 5 columns, and I need to migrate this data to a table that has 20 columns. How to do this? of course I need that the remaining 15 columns of the destination table be filled with NULL data.

From what I have seen, it seems that my xml format file must always have the same amount of <COLUMN> elements than the number of columns in the destination table, is this always so?. If it is, this is a real problem, since I lack 15 <COLUMN> elements in my format file.
I really don't know what can I do about this, pelase help!!

Thanks in advance,
Diego V.

Create a VIEW with the table.columns that match the data file, and BCP into the VIEW. (Be sure the other columns allow NULL values and/or have DEFAULT values.
