[ @publication = ] N'publication'
The name of the publication. @publication is sysname, with no default.
[ @scriptfile = ] N'scriptfile'
The full path to the SQL script file. @scriptfile is nvarchar(4000), with no default.
[ @skiperror = ] skiperror
Indicates whether the Distribution Agent or Merge Agent should stop when an error is encountered during script processing. @skiperror is bit, with a default of 0.
0= the agent stops.1= the agent continues the script and ignores the error.

Remarks
sp_addscriptexec is used in transactional replication and merge replication.
sp_addscriptexec isn't used for snapshot replication.
To use sp_addscriptexec, the SQL Server service account must have read and write permissions on the snapshot location and read permissions on the location where any scripts are stored.
The sqlcmd utility is used to execute the script at the Subscriber, and the script is executed in the security context used by the Distribution Agent or Merge Agent when connecting to the subscription database. When the agent is run on a previous version of SQL Server, the osql Utility is used instead of the sqlcmd utility.
sp_addscriptexec is useful in applying scripts to subscribers, and uses the sqlcmd utility to apply the contents of the script to the Subscriber. However, because Subscriber configurations can vary, scripts tested before posting to the Publisher might still cause errors on a Subscriber. @skiperror allows for the Distribution Agent or Merge Agent ignore errors and continue on. Use the sqlcmd utility to test scripts before running sp_addscriptexec.
Note
Skipped errors continue to be logged in the Agent history for reference.
Using sp_addscriptexec to post a script file for publications using FTP for snapshot delivery is only supported for SQL Server Subscribers.
Permissions
Only members of the sysadmin fixed server role or db_owner fixed database role can execute sp_addscriptexec.
