Material serial numbers

Hi,

we are working with material serial numbers in MM and SD.

those serial numbers have different statuses. because some status was set wrong with a material movement, I need to set manually a status for that specific material serial number.

With transaction IQ02 it does not work.

does anyone know if in which tables the status information is stored? Can I set the status directly in a table with SE16n?

Thanks,

Markus
