Both settings are off by default, so the first order that contains one of these lines fails to sync. Both kinds of line come from the point of sale: - **Zero quantity**: a line cancelled on an open order. Cancelling a line sets its quantity to `0` and mirrors that to the linked Order Product, so the cancelled line stays on the order as a record of what was removed rather than disappearing. An order whose lines were all cancelled has every Order Product at quantity `0`. - **Negative quantity**: a return or refund line. Returns are written as negative-quantity lines that reduce the order total. The online store cannot produce either. Zero and negative quantity items are removed from the cart before checkout. ## Resolution ### Step 1: Enable the relevant setting in Order Settings 1. In Salesforce, go to **Setup**. 2. In the Quick Find box, search for **Order Settings**. 3. Open **Order Settings**. 4. Check the setting that matches the error message: - For "quantities of zero", check **Enable Zero Quantity**. - For "negative quantities", check **Enable Negative Quantity**. 5. Click **Save**. :::note You can turn these settings back off later, but Salesforce then refuses to activate any order that still contains a zero or negative quantity line. Existing records stay visible and editable. Leave the settings on for as long as your registers can cancel lines or process returns. ::: ### Step 2: Re-sync the failed records 1. Go to the [sync error tool](sync-error-tool) in StoreConnect. 2. Select the checkbox next to all affected Order Product records. 3. Click the **Re-sync** button. The records should now sync successfully. :::tip Select all records in the Sync Errors list when re-syncing, not just the first one. Related downstream errors (such as `INVALID_FIELD` on order item taxes or payment items) will also clear once the root Order Product records sync. ::: ## Verification 1. Confirm the sync errors no longer appear in the [sync error tool](sync-error-tool). 2. Open the affected order in Salesforce and confirm the Order Products are present with the expected quantities, including any cancelled lines at quantity `0`. ## Prevention - **Enable both settings before you take POS orders**: a register can cancel a line or process a return at any time, so check **Enable Zero Quantity** and **Enable Negative Quantity** in **Order Settings** as part of your initial configuration. - **Check the sync error tool after your first cancellation or return**: a rejected Order Product also blocks the order item tax and payment item records behind it, so catching the setting early keeps one order from producing a page of errors. --- ## Follow StoreConnect - [Email Newsletter](https://storeconnect.com/c/lp-newsletter) - [LinkedIn Newsletter](https://www.linkedin.com/build-relation/newsletter-follow?entityUrn=7444956928444862464) - [YouTube](https://www.youtube.com/channel/UCngKdP2x8l1wcbAKW3tvU8g) - [LinkedIn](https://www.linkedin.com/company/storeconnect) - [X / Twitter](https://x.com/storeconnecthq) ## Popular Links - [Partners](https://storeconnect.com/partners) - [Become a Partner](https://storeconnect.com/become-a-partner) - [News](https://storeconnect.com/articles/news) - [Events](https://storeconnect.com/articles/events) - [Live Events](https://storeconnect.com/live-events) - [Feature Comparison](https://storeconnect.com/how-we-compare) - [Download a free trial](https://appexchange.salesforce.com/appxListingDetail?listingId=a0N3A00000FMkeKUAT) - [Book a Demo](https://storeconnect.com/contact) ## Documentation - [Help documentation](https://support.storeconnect.com/help-documentation) - [AI agents](https://support.storeconnect.com/ai) - [Videos & tutorials](https://support.storeconnect.com/videos-tutorials) - [Developer reference](https://support.storeconnect.com/developer-reference) - [Release notes](https://support.storeconnect.com/release-notes) - [Troubleshooting](https://support.storeconnect.com/troubleshooting) - [Trust Center](https://trust.getstoreconnect.com/) - [Status Page](https://status.storeconnect.com/) ## Contact - info@getstoreconnect.com - US +1 415 745 3230 - AUS +61 2 8365 2308 100 S Ashley Dr, Suite 600-2461 Tampa FL 33602-600 USA Level 22, Sydney Place 180 George Street Sydney, NSW, 2000, AUS ## Machine-readable - [Site index for agents](https://storeconnect.com/llms.txt): curated map of the StoreConnect site in llms.txt format - [Documentation index for agents](https://support.storeconnect.com/llms.txt): full technical and product documentation map Every page and article on this site has a Markdown rendering: append `.md` to its URL.
