When I try to run just your declare:

(Declare @AbsTab table (org_id int, absr_id int, abs_id int, abs_date datetime primary key (absr_id, abs_id,abstab_id)))

I get:

Msg 1911, Level 16, State 1, Line 1

Column name 'abstab_id' does not exist in the target table or view.

Msg 1750, Level 16, State 0, Line 1

Could not create constraint. See previous errors.

I'm curious, one of the errors you got referred to 'dbo.@AbsTab'. Is that a "hard" table rather than a table variable?
