would a change in the order of fields require a schema update in BODS / database is teradata

I am going through a critical deployment situation and need to take a call.

The order of fields in teradata has changed.

Eg:- It was create table col1,col2,col3,col4 before. Now it has changed to col1,col2,COL4,COL3.

Would this change require a reimport in BODS or would the present schema of col1,col2,col3,col4 work?

I feel it's not needed. Kindly provide your comments.
