Difference between logical and physical foreign key constraints?

[Guest_imported]

I am running Sybase ASE 11.9.2
I add a foreign key using alter table and sp_foreignkey

alter table table_A add constraint FK_table_B_table_A
foreign key
(
table_B_id
)
references table_B
(
table_B_id
)

sp_foreignkey table_A, table_B, table_B_id

in this example table_B is the parent and table_A
is the child

When I open DBArtisian this noted as a Logical Foreign Key?
Artisian says that because it is a Logical that the RI is not enforced.
I am unaware of any differences in syntax for the alter table add constraint for logical vs physical.
What is happening here?
Thanks

I figured it out by dropping the foreign key and recreating it with the DBArtisian GUI.

DBArtisian refers to a logical foreign key as just a row in syskeys.

this is done by executing sp_foreignkey

using the alter table creates the fk constraint.
