Account assignment template in FB60 does not store Vendor account

Chaps,

When I save an 'Account assignment Template' in FB60, the Vendor does not get saved. (When I call back the Template, the Vendor is blank)

Is this standard functionality? Any way to remedy?

I was also looking for some documentation on the logic of the templates (recall, change.. depending on which user created it ..).  If you could direct me to some good posts ..

Thanks again for your help. I read a lot of post but couldn't find definite answer..
