pk-fk problems

Hallo,

table A
x : int, increment, identity, index
relationship: fk_b_a has pk in A:X , fk in B:X
enforce for repl , insert i update-selected

Table B
x : int, index
relationship: fk_b_a has pk in A:X , fk in B:X
enforce for repl , insert i update-selected

relationship name in B is marked with infinity symbol.

Cant remove record from A, bacause
DELETE statement conflicted with COLUMN REFERENCE constraint 'FK_B_A'.
The conflict occurred in database 'xxx''.

Relevant record from B is removed properly.

CREATE procedure deleteAB(@.ser int,@.rv int output)
as
begin
delete from A where x=@.ser
delete from B where x=@.ser
set @.rv=0
end

what is wrong ?
