She traced the source of RegionCode . It was a foreign key to a lookup table, Dim_Region , populated nightly by another SSIS package called RegionSync . Emma opened that package’s logs.

SELECT TOP (10) * FROM dbo.Fact_Transactions WHERE TransactionDate >= DATEADD(DAY, -1, GETDATE()) The result set returned , all with RegionCode = NULL . Aha! The data existed, but the region field—critical for the downstream aggregation—was missing.

Chapter 1 – The Morning Alarm Emma Patel’s alarm chimed at 6:00 a.m., and she hit the snooze button with the reflex of a seasoned night‑owl. By 7:15 a.m. she was already at her standing desk, coffee in one hand and her laptop humming under the other. Today was the day the finance team would finally get their quarterly “Revenue‑by‑Region” report—automatically refreshed every night by the company’s flagship SSIS package, RevenueRollup . ssis-308

She ran the same query directly in :

[06/13/2026 02:01:04] **Error: SSIS-308 – The data flow task failed to complete successfully.** Emma’s heart skipped a beat. —the dreaded “data flow task failed” message that usually meant something deeper was wrong. She’d seen the code before, but never in a production run. She took a deep breath, poured another cup of coffee, and began her investigation. Chapter 2 – The First Clue Emma opened the Data Flow Designer and inspected the OLE DB Source that queried the Fact_Transactions table. The SQL statement was simple: She traced the source of RegionCode

[06/13/2026 01:45:12] Warning: SSIS Warning Code 0xC0047013 at Lookup [RegionLookup] : The lookup operation returned no matching entries for the following keys: (RegionCode = 0). A warning, not an error. But now she was seeing a cascade of NULL region codes, which caused the RevenueRollup package’s to fail when FailComponentOnError was set to True . The package then threw SSIS‑308 , bubbling up the failure to the job.

Emma checked the and saw:

A quick glance at the job history, however, told a different story.
