Investigating Sync Issue for FBM Inventory from Odoo to Amazon Connector
The product is listed under FBM fulfillment inventory and is active in the Amazon Mexico channel.
Product details are as follows:
ASIN: B0DGHLQ22Q
SKU: IA-9G82-XKTE
When we attempt to send any inventory quantity from Odoo to Amazon, we encounter the following error from Amazon:
"An FBA offer already exists on this SKU. To create a seller-fulfilled SKU, either create a new SKU or change the SwitchFulfillmentTo value to MFN."
In the Mexican channel, only FBM products are listed, and no FBA products exist. However, this error persists, requiring further investigation.
