The Product Download Log documents large, batch-based product downloads.
Start/End, Shop, Batch, Cursor/Last ID, SKU, Processed/Successful/Failed, Status, and Message.
Note the last successful record.
Check the error cause in the Activity/API Log.
Correct the mapping, attribute, or master data.
Restart the product download.
Verify that the cursor resumes correctly.
Only change cursor/start values if you understand how they work and what the consequences are.
Restarting with an incorrect start point can skip records or reprocess them unnecessarily.
Compare total count, last ID, open errors, and spot checks in BC.
