flat file source order of columns

I have a flat file source as

SOURCE1~SOURCE2~SOURCE3

1~2~3

1~2~3 target is

1~2~3

1~2~3

which is normal case.

now the scenario as my extract has changes to

SOUCE2~SOURCE1~SOURCE3

1~2~3

1~2~开发者_JS百科3

now the target is still

1~2~3

1~2~3

but needs to get as

2~1~3

2~1~3

the data in the target table is not dynamically getting.

the target is

it is not following the header names.

Could I get any information on changing the order of columns in .txt files.

thanks prav

The connection manager in SSIS is not dynamic. Once the connection manager is defined, the order of columns determines the mapping into the data flow. You will need to modify the package for the new layout.
