SSIS runs successfully but table does NOT updated

All,

I have one SSIS package which has 5 different Execute SQL task (Running in Sequential execution) and Send Mail Task at the end.

Each execute SQL task runs separate Stored Procedure which updates 5 separate tables.

Once those are completed successfully then Developers get an email.

This Package is running fine when I run manually.

Last 6 months we scheduled to run this package through SQL Agent.

Just today I got an issue that one of the table did not get updated.

Developers received success email and I checked dbo.sysssislog table i can see that particular step took 2 hours to execute but back end table does NOT updated as per stored procedure.

P.S I am using SQL 2014

Thanks in advance

Thanks

Fredyyy
