When the connection is set to "Automatic Mode", Finale is designed to only push stock levels for the following three scenarios
Finale will update any given product within 5 minutes of a stock change
Finale will update any given product within 5 minutes if any of the product's attributes/details have changed
Once nightly, Finale will update ALL product lookups to ensure Finale and the marketplace are in sync
However, if you want Finale to update a sku immediately, you can select the "Queue quantity update to integrations" from the product details page.
Finale will update this marketplace sku upon the next update if the setting is set to "Automatic mode". Alternative you can select "Run Task Now" to immediately update the selling channel.
Please note the product mapping between the marketplace sku and Finale product id must exist to use this operation. Otherwise, this operation will grayed out and will not be selectable.
