You will need to find out what the biz rule for defaulting NULLs is.
THen In the Transformer stage based on the null default write a IF THEN ELSE clause as -
If NULL THEN <default value> ELSE column.

You select the Nullable is YES and your not handleng the NUlls in Format tab.

Pls select the Field default then Null fileld Value="\000"

Go to the Columns grid and edit the extended metadata for the Nullable column. Set its Null Field Value property (in the Nullable folder). If the sequential file is fixed width then the number of characters in the Null Field Value property must exactly match the number of characters in the field itself.
