Add the Amazon FBA Inventory Ledger report (GET_LEDGER_SUMMARY_VIEW_DATA) — true on-hand incl. in-transit between FCs#1769

The Amazon Seller Central connector currently has no reliable way to see true total FBA on-hand. The Manage Inventory (MYI) report’s afn-total-quantity only counts warehouse + inbound — it excludes units in transit between fulfillment centers — and the Restock report intermittently returns 0 for SKUs that are actually well-stocked. So for any seller whose inventory Amazon is redistributing across FCs (which is constant), the numbers under-report real owned stock, throwing off reorder and replenishment decisions.

Please add Amazon’s Inventory Ledger – Summary View (GET_LEDGER_SUMMARY_VIEW_DATA) — Amazon’s authoritative “bank statement” of inventory, and the only report that breaks out:

in-transit-between-warehouses ← the units MYI and Restock miss
ending-warehouse-balance
starting balance, receipts, customer shipments, returns, removals — by ASIN / MSKU / FNSKU / date.
Together, ending-warehouse-balance + in-transit-between-warehouses = the real total on-hand.

It’s a standard SP-API Reports-API report — same mechanism and same “Inventory and Order Tracking” role the connector already uses for MYI and Restock, so no restricted/PII access is needed. This would let every Amazon seller reconcile actual inventory and stop over- and under-ordering. 🙏
