Stored Procedure Inside SSIS Successful but does not Perform INSERT - First time since Pkg Created

Question

All - We have a Stored Proc that Runs inside a SSIS package and INSERTS in a table and it was developed a Year Ago - After almost one year this Stored Procedure runs and DOES NOT INSERT - and when I pull the procedure out and Manually runs it -
it runs totally fine.
Did anyone face anything like this before ?
It does create around 10 temp tables before running the INSERT and it INSERTS around 2.5 Million rows. And its a Wide table with 180 Columns

Answer 1

When you execute the Stored Procedure directly in SSMS (SQL Server Management Studio), it execute under the login that you open SSMS, it was be a Window login or SQL Server one.
So from SSIS packages, you have to ways :
1. When you execute the package from SSIS, it execute under the service that SSIS run.
2. When you scudule the package in SQL Agent, the package execute under the account service of SSIS, or another one (you can specify) by impersonation.
Ok, for the solution, i prefere change the impersonate before call procedure, exactly change the current login to another that have the priviliges to execute and insert the Data in the table like :
1. Edit the SP.
2. before the T-SQL type :
EXECUTE AS USER = 'yourLogin';3. retryTo understand the impersonation :http://msdn.microsoft.com/fr-fr/library/ms181362.aspx
