KANBAN CARD Printing problem

Hi,

I am facing one problem regarding Kanban Card printing.

When i do run transaction MIGO for po and then check and Post then first time its printing ####### for matrial no,container,content,supp.area and Storage Bin .

But once spool is generetd second time ..its printing fine with all above data.

One more thing i wanted to clear ..Kanban layout was working fine before applying service pack 14.

Can any body suggest me solution .

Many thanks in advance.

Best Regards,
