Changes properties of the Snapshot Agent for the specified publication. This stored procedure is executed at the Publisher on the publication database.
Important
When you configure a Publisher with a remote Distributor, the values supplied for all parameters, including @job_login and @job_password, are sent to the Distributor as plain text. You should encrypt the connection between the Publisher and its remote Distributor before executing this stored procedure. For more information, see Configure SQL Server Database Engine for encrypting connections.

The date when the Snapshot Agent is first scheduled, formatted as yyyyMMdd. @active_start_date is int, with a default of NULL.
The date when the Snapshot Agent stops being scheduled, formatted as yyyyMMdd. @active_end_date is int, with a default of NULL.
The time of day when the Snapshot Agent is first scheduled, formatted as HHmmss. @active_start_time_of_day is int, with a default of NULL.
The time of day when the Snapshot Agent stops being scheduled, formatted as HHmmss. @active_end_time_of_day is int, with a default of NULL.
The name of an existing Snapshot Agent job name if an existing job is being used. @snapshot_job_name is nvarchar(100), with a default of NULL.
