Hello, I am attempting to do an Inventory Adjustment CSV import to account for some variance in our inventory numbers. However, I keep getting an error that the records internal id cannot be found. I am using the item records internal id, what am i missing?

Is that item record marked Inactive?

Sounds like you need to specify the External ID because you are trying to create a new inventory adjustment. External ID is required when creating new records via import, it can be any value like Invadj_92922
