MetaData:

 --   
--  Name: sp_MSdodatabasesnapshotinitiation  
--   
--  Description: This procedure is called by the snapshot agent to perform the  
--               the necessary (article & subscription) initiation procedures  
--               when generating a snapshot from a database snapshot.  
--  Parameter: @publication sysname (mandatory)  
--   
--  Notes: This procedure is assumed to be run within a transaction from the  
--         snapshot agent. As such, no explicit error handling is performed  
--         in it. This procedure will also return 1 immediately if one of the   
--         following is not true:  
--         1) Caller is not member of db_owner role  
--         2) Caller is not a replication agent connection  
--         3) @@trancount < 1  
--   
--  Returns: 0 - succeeded  
--           1 - failed  
--     
--  Security: Public interface, non-db_owner caller will result in no-op  
--
