I have the following SQL script

CREATE MULTISET TABLE "test" 
(
"TestID" BIGINT GENERATED ALWAYS AS IDENTITY 
    (START WITH 1 INCREMENT BY 1 MINVALUE 1 MAXVALUE 2147483647  NO CYCLE) NOT NULL,
"Version" VARCHAR (30)
);

When I run it against Teradata Express (17.20.3.02) it executes successfully and creates the table, although it implicitly creates a Primary Index behind the scenes for the TestID column. However, the same exact script run on another Teradata instance hosted by ClearSpace (17.20.3.23) returns the following error:

Syntax error: Identity Column in a NoPI table is unsupported.

I get that I could add a section in to cover the auto generate column but did the behavior change between versions? SQL scripts that worked before, no longer do on the hosted version?
