[ ] Verify SSIS version – apply CU with KB‑xxxxx if < 2024‑03. [ ] Change destination columns to NVARCHAR where feasible. [ ] If VARCHAR must remain, add a Data Conversion component with explicit code page (1252). [ ] Add a Script Component to log any Unicode→ANSI loss. [ ] Enable package logging (OnError, OnWarning) and monitor catalog.operation_messages. [ ] Run a validation job on a sample payload containing characters like é, ß, 汉. [ ] Document any rows that get truncated and decide on business rules (drop/replace).
Additionally, considering that SSIS can be part of the Microsoft Data Platform, discussing integration with other components like SQL Server Analysis Services (SSAS) or SQL Server Reporting Services (SSRS) might be relevant, though the essay should stay focused on SSIS-661's likely content. SSIS-661
| Item | Description | |------|-------------| | | 661 | | Message text | “The user does not have the necessary permissions to perform this action.” | | Typical sources | - Deploying a package to the SSIS Catalog (SSISDB) - Executing a package that accesses a secured data source (e.g., Azure Blob, SQL Server, Oracle) - Using the SSISDB stored procedures (e.g., catalog.create_project , catalog.start_execution ) - Running a package from DTExec / DTExecUI under a Windows account lacking required rights | | Why it matters | SSIS runs with the security context of the SQL Server service account , the SQL Agent proxy , or the Windows user you launch it under. If that identity can’t read/write to the Catalog, or can’t access external resources, the package aborts with error 661. | [ ] Verify SSIS version – apply CU
Open and view the Message column or the Execution Log . Note the operation that triggered the error (e.g., catalog.create_folder , catalog.start_execution , catalog.deploy_project ). [ ] Add a Script Component to log any Unicode→ANSI loss
Then edit the job step → → select ETLUserProxy .
: This could stand for several things, such as "Sql Server Integration Services," which is a tool for building enterprise-level data integration and data transformation solutions. If that's the case, "SSIS-661" might refer to a specific package, task, or issue within that system.
