selecting PM orders according to status

hello

I need to select PM orders according to several parameters, one of which is a specific User Status.

I see that there are many tables containing statuses, like TJ20, TJ30, and plenty of others but I cannot find a reference field to connect the status to the PM order.

meaning: TJ30T for instance has a field TXT04 which contains the user status but, no field for the PM order.

how can I connect a specific order to a table containing user status?

thanks

Alisa
