This SSIS package execution error can occur for a few reasons:
- Path to the file does not exist.
So for example, if you’re writing the file to C:\Some\Folder\somefile.txt, C:\Some\Folder needs to exist first.
Fix: Create the folder that the package will write to prior to executing it.
Alternatively, you can add a File System Task with a
Create Directory operation prior to the Flat File Destination component.
- The account executing the package does not have permissions
Check to make sure whichever account is executing the package has sufficient file system permissions to write the file to disk.
Fix: Grant the appropriate write permissions to the user account that is executing the package. On a server, this would be the SQL Server Agent account that’s executing the package.
- The file you’re writing to is being used by another process
If some other process is using the file you’re writing to, it will block SSIS’ attempt to write to it simultaneously.
Fix: In general, make sure that the file is not in use by some other application or process.
Be careful copying and pasting SSIS tasks and components inside of a package – If you do, make absolutely sure you’ve adjusted each configuration appropriately. I’ve run into this “file is being used by another process” situation because I copied and pasted an Execute Package task, and forgot to update the config – attempting ot execute the same package in parrallel can cause issues, apparently! haha
