Whenever an update is made to an item quantity, inventory flow updates the eBay inventory with those items. For each item an individual call is made to eBay and the quantity is updated.
If you made any changes to the inventory of matrix parent which has 5 children, then, 5 different calls are made at a time to update the item quantity for each child. This causes incorrect quantity update for few child items in matrix.
To resolve this issue, perform the following steps:
- Sign in to your integrator.io account.
- Navigate to your integration app tile.
- Click the Connections tab.
- Verify, if you updated the concurrency value limit. If yes, then you must set the concurrency value limit to 1. This will resolve the issue.
Note: Changing the concurrency value limit to 1 will impact the connector performance. You can avoid this situation by adding a secondary connection and set its concurrency value limit to 1. Make sure you assign the new connection to the inventory flows.
