Foreign Key Constraint Error

Hi Guru's

In my package I have a transformation OLEDB Command. This is used to update if employee details but i'm getting the following error.

[Update Case Detail [696]] Error: SSIS Error Code DTS_E_OLEDBERROR.  An OLE DB error has occurred. Error code: 0x80040E2F.
An OLE DB record is available.  Source: "Microsoft SQL Server Native Client 10.0"  Hresult: 0x80040E2F  Description: "The statement has been terminated.".
An OLE DB record is available.  Source: "Microsoft SQL Server Native Client 10.0"  Hresult: 0x80040E2F  Description: "The UPDATE statement conflicted with the FOREIGN KEY constraint "FK_EmployeeDetail_EmployeeeStatus". The conflict occurred in database "DBNAME", table "dbo.EmployeeStatus", column 'EmployeeStatus'.".

Can anyone please guide me how to get around this error?

Thanks
