How to Troubleshoot Common Send to Amazon Workflow Errors
Guide to diagnosing and resolving common errors in Amazon's Send to Amazon shipment creation workflow, covering yellow warnings, red blocking errors, and step-by-step isolation techniques for SKU-level issues.
Overview
Amazon's Send to Amazon workflow is the primary tool sellers use to create FBA shipments, but it can sometimes throw errors that stall the process. Understanding how to diagnose and resolve these issues on your own can save significant time and get your inventory moving to fulfillment centers faster. This guide covers the most common troubleshooting strategies for both warning and blocking errors in the shipment creation workflow.
Key Points / What Sellers Need to Know
- Yellow warnings vs. red errors — Yellow warnings are informational and won't prevent you from moving forward with shipment creation. Red errors, on the other hand, can completely block your progress and must be resolved before continuing.
- Most errors are SKU or ASIN-level issues — The majority of errors encountered in the Send to Amazon workflow stem from problems with individual SKUs or ASINs, not system-wide bugs. Investigating at the product level is usually the fastest path to resolution.
- Inventory must be fully prep-compliant — Amazon requires that all inventory is properly prepared for fulfillment center receiving before shipments can be created. Missing prep requirements are a frequent source of blocking errors.
- Error messages include helpful links — Most red errors come with built-in links that either explain the issue in more detail or direct you to the Fix SKU Defects page where you can resolve product-level problems.
- Test workflows are a powerful diagnostic tool — Creating a small test workflow with individual SKUs can help you isolate which specific product is causing an error in a larger shipment plan.
Troubleshooting Strategy: Isolate and Test
The most effective approach to resolving Send to Amazon errors is systematic isolation. Start by reviewing your full SKU list and going back through previous steps of the workflow to check whether any new errors have surfaced. If the source of the problem isn't immediately clear, create a new test workflow and add each SKU from your original manifest individually. This allows you to pinpoint exactly which product is triggering the error. If the test workflow allows you to proceed past the step where you were originally stuck, you should continue with the new workflow for shipment creation and void the old one.
Analysis & Recommendations
Why This Matters
Shipment creation errors can delay inventory replenishment and cause stockouts, directly impacting sales and rankings. Knowing how to self-troubleshoot these issues reduces downtime and reliance on Seller Support.
Key Takeaways
- Most Send to Amazon errors are caused by SKU or ASIN-level issues, not system bugs
- Creating test workflows with individual SKUs is the most effective way to isolate problem products
- Void test shipments promptly — within 24 hours for SPD and 1 hour for LTL — to avoid carrier charges
- You can access any workflow by its 'wf' ID in the URL, even if it doesn't appear in the active workflows list
Recommended Actions
- →When encountering a blocking error, create a new test workflow and add SKUs individually to identify the problematic product
- →Bookmark the step-specific troubleshooting pages for quick reference when errors occur during shipment creation
- →Always void or cancel test workflows immediately after troubleshooting to avoid unexpected carrier charges
