Troubleshoot Forecast Data Issues
This guide helps you fix common forecast data issues including negative numbers, outdated data, missing customer setups, and calculation mismatches

| Quick Reference - Common Issues discussed here |

What you're seeing: Negative values in All-Other Bucket forecasts.
Why this happens: This is usually normal. All-Other Buckets calculate as: Distributor Shipments - Retailer Consumption. When you ship 1,000 units to a distributor in Week 1, but stores sell 250 units per week over Weeks 2-5, you'll see negatives in some weeks. This reflects timing between shipment and retail sales.
How to fix it:
-
-
Check "Weeks to Retail" - Go to Manage > Customers, select your retailer, find Weeks to Retail field. Should be 2-4 weeks typically. Update if incorrect and regenerate forecast.
-
Verify customer assignments - In Manage > Customers, confirm each retailer has correct distributor in First Receiver section and splits total 100%. Ensure each distributor has an All-Other Bucket assigned.
-
Assess the pattern - Occasional negatives are normal. Consistent extreme negatives every week suggest setup issues like incorrect distributor splits or weeks to retail.
-
When to override: If future week forecasts don't match business expectations, click into the cell and enter your override value.
Remember: Negative values in past weeks (actuals) often reflect real supply chain timing and shouldn't be changed.

Issue 2: Outdated Forecast Data
What you're seeing: Forecast doesn't reflect recent revenue uploads, promotions, or pricing changes.
Why this happens: Forecasts create snapshots and don't auto-update when you change data.
How to fix it:
-
-
Go to Insights > Forecast
-
Click Generate Forecast (top right)
-
Wait 1-2 minutes for completion
-
Refresh your browser and check numbers
-
Best practice: Generate weekly, after major uploads, or before important meetings.

Issue 3: Missing Customer Setup
What you're seeing: Distributor forecasts show zeros or unexpectedly low values.
Why this happens: Missing required customer relationships.
How to fix it:
-
-
Check distributors - Go to Manage > Customers, search for distributors, verify each has an All-Other Bucket. If missing, click Create All-Other Bucket.
-
Check All-Other Buckets - Find each All-Other Bucket customer, scroll to First Receiver section, ensure parent distributor is listed. Add if missing.
-
Check retailers - Filter to retailer customers, verify each has at least one first receiver (distributor or "Self"). Add if missing with splits totaling 100%.
-
Regenerate forecast after changes.
-

Issue 4: Wrong Revenue Source Configuration
What you're seeing: Significantly lower forecast numbers or zeros despite uploads.
Why this happens: Revenue sources must match customer types:
-
-
Retailers use Forecast Revenue Sources (SPINS, IRI, Circana)
-
Distributors use Accounting Sources (NetSuite, QuickBooks, SAP)
-
How to fix it:

For Retailers:
-
-
Go to Manage > Customers, select retailer
-
Check Forecast Revenue Source field (should show SPINS, IRI, etc.)
-
Go to Revenue > Revenue Dollars, filter to retailer
-
Verify Source column matches the Forecast Revenue Source
-
Re-upload with correct source if mismatched
- Regenerate forecast after corrections.
-

For Distributors:
-
-
Go to Settings > Deductions & Revenue
-
Scroll down to the Select Accounting Sources section
-
Verify ERP system is checked under Accounting Sources
-
Go to Revenue > Revenue Dollars, filter to distributor
-
Verify Source column shows an Accounting Source
-
Re-upload with correct source if mismatched
- Regenerate forecast after corrections.
-
Common mistake: Don't upload ERP data to retailers or POS data to distributors (unless retailer is direct).

Issue 5: Conflicting Pricing
What you're seeing: Unexpected revenue calculations or distributor/first receiver mismatches.
Why this happens: Multiple price entries for same product, overlapping timeframes, or distributor/direct retailer price differences. System uses highest price, potentially inflating projections.
How to fix it:
-
-
Go to Manage > Pricing
-
Search affected product, look for multiple entries with overlapping dates
-
Note customer, dates, and price for each entry
-
Resolve by:
-
Deleting duplicate entries (keep most accurate)
-
Adjusting date ranges to eliminate overlaps
-
Aligning prices between distributors and direct retailers
-
-
Regenerate forecast
-

Issue 6: Conflicting Distributor Splits
-
- Go to Manage > Customers, select retailer, view Timeframes
- For each timeframe, click Edit and verify splits total 100%
- Go to Product Management, search product, check which Product Groups include it
- Resolve by:
- Removing product from extra groups
- Aligning splits across all groups
- Using timeframes if splits legitimately changed over time
- Regenerate forecast

Issue 7: Monthly vs. Weekly Data Mismatches
What you're seeing: Manually calculated monthly totals don't match monthly view.
Why this happens: Weeks spanning two months split proportionally by days. Week ending Feb 5 with 5 February days and 2 January days splits a 700-unit forecast as 500 to February, 200 to January.
How to workaround this:
-
-
Use Group by: Month/Quarter dropdown in Insights > Forecast instead of manual calculation
- Click on Export button
-
Note: Don't manually sum weekly exports
When to expect differences: Small variances at month boundaries, year boundaries, and forecast start dates are normal.

Issue 8: Conflicting Weeks to Retail
What you're seeing: Unexpected timing differences or revenue in wrong periods.
Why this happens: Different weeks to retail values across customer timeframes cause inconsistent calculations.
How to fix it:
-
-
Go to Manage > Customers, select retailer, view Timeframes.
-
Check Weeks to Retail for each timeframe, look for inconsistencies.
-
Confirm correct timing with sales/logistics team.
-
If consistent: Use same value across all timeframes.
-
If legitimately changed: Document reason and align timeframe dates with when change occurred.
-
Regenerate forecast.
