This article describes how the user can enable the MF (also known as FBM) Automation Feature, allowing sellers to activate both MF/FBM and FBA (Fulfilled by Amazon) simultaneously.
This dual-fulfillment approach (enabling both MF & FBA simultaneously) helps sellers maintain continuous stock availability, eliminate stockouts, and sustain sales velocity - all critical components for protecting and even enhancing product ranking (as well as seller's rank).
To enable this feature fist navigate the user must navigate to their Global Settings by clicking on the cogwheel. This article describes navigation to Global Settings.
Once the user arrives to their Global Settings page, locate the Catalog tab and click on it. Under Amazon, the user will now see several Marketplace Specific Settings. 
FBM Inventory: If this toggle is turned on, SKUPREME will sync storage provider inventory to Amazon MF listings. Only storage providers with the configuration set to direct to consumer fulfillment will be synced (SKUPREME will not push inventory from warehouses that are not set to do fulfillment to FBM). In other words, if this toggle is turned off, users can still manually manage inventory from Amazon Seller Central.
FBM Catalog: If this toggle is turned on, and an MF listing is not yet detected, SKUPREME will generate an MF listing for FBA listings that have available storage provider inventory.
FBM Order: If FBM order sync toggle is turned on, SKUPREME will be routing your FBM orders to the fulfillment centers based on priority.
AWD: If this is turned on, and your Amazon account is using AWD (Amazon Warehousing & Distribution), then SKUPREME will be syncing AWD shipments and inventory data.
Please make sure that both the "FBM Inventory" (to push inventory from SKUPREME to FBM) and the "FBM Order" (to pull MF Orders on Amazon to SKUPREME) are enabled to fully take advantage of using MF with FBA simultaneously. While it is very useful and convenient for users, the "FBM Catalog" feature, which allows us to generate MF listings for FBA listings that have available storage provider inventory, is not absolutely necessary to leverage this feature.
