Amazon Vendor Demand Forecasts
How VENDOR_FORECASTING_SRC shows Amazon's latest weekly demand forecast, and how to get past forecasts to compare with your sales.
Every week, Amazon publishes a new demand forecast for each of your ASINs in Vendor Central. Each forecast covers the next 48 weeks. DataHawk collects it and delivers it to SELLING_PARTNER.VENDOR_FORECASTING_SRC every Wednesday. This page explains what the table shows and how to compare a past forecast with your sales.
What's in the table
The table holds one row per ASIN and forecasted week. Each row carries:
- Generation date: the day Amazon produced the forecast.
- Start date: the first day of the forecasted week.
- Forecasted units: Amazon's Mean, P70, P80, and P90 demand forecasts for that week. In short, the higher the P-level, the more cautious the number.
DataHawk serves these values as Amazon sends them, without recalculating them. For Amazon's exact definitions and report rules, see Amazon's Vendor Forecasting Report documentation.
Only the latest forecast is kept
The table always shows Amazon's latest forecast. Each week, the new forecast replaces the previous one entirely. Older forecasts don't stay in the table.
Here's how it works week by week:
| Week | DataHawk collects | What the table shows |
|---|---|---|
| W0 | Forecast for W0 to W48 | Forecast for W0 to W48 |
| W1 | Forecast for W1 to W49 | Forecast for W1 to W49. The W0 forecast is gone |
| W2 | Forecast for W2 to W50 | Forecast for W2 to W50. The W1 forecast is gone |
And so on, every week.
Compare a past forecast with your sales
Want to check how accurate Amazon's forecast was? You'll need the forecast as it looked on a given date, then compare it with your actual sales as the weeks go by. You have two ways to get it.
Option 1: save the forecast yourself
When you want to track a forecast, save a copy of it after Wednesday's delivery, before the next one replaces it. For example:
- Download the Forecasting report from Vendor Central.
- Export the table from your DataHawk destination (Snowflake, BigQuery, or another tool).
Later, compare that saved copy with your sales data. Plan ahead: once a newer forecast is out, neither Amazon nor the table will show the old one.
Option 2: ask DataHawk
Amazon only shares its most recent forecast. DataHawk, however, keeps every past forecast on its side. Forgot to save one? We can send it to you.
