BAI2 file format- 6 record / Check DDA Account

SAP Guru's

Can any one confirm for me what the position and characters should be for check DDA Account. In my last assignment, I used the following:

Position 27-39 Field Size 13 Right justify and zero filler

The BAI/ BAI2 file format white paper for SAP I believe is out of date because it says that the check DDA account should be 10 characters.

Can any one confirm for me which is right and if I am right which I assume I am since my last lockbox implementation was successful, why is the white paper say 10? Is there a latest version?

Thanks!
