Error When Changing Published Article At The Subscriber

Hi


Using merge replication - the stored procs are published articles.


When trying to change the article at the subscriber (sql express) I get the following errors:

Msg 21531, Level 16, State 1, Procedure sp_MSmerge_alterschemaonly, Line 45
The DDL statement cannot be performed at the Subscriber or Republisher.

Msg 21530, Level 16, State 1, Procedure sp_MSmerge_ddldispatcher, Line 181
The DDL operation failed inside merge DDL replication manipulation.

Msg 3609, Level 16, State 2, Procedure usp_Anniversary_upd, Line 21
The transaction ended in the trigger. The batch has been aborted.



Does this mean it can only be changed at the publisher ?
