Zoho Inventory : Export/Import Item Adjustments

Zoho Inventory : Export/Import Item Adjustments

Hello,

I enable batch tracking.
I create an Item
I manually adjust its quantity
I export this adjustment in CSV
I delete this adjustment manually
I import the csv without any change
I get fields mapping issue : this fields are not automatically mapped (which is annoying) :
Reference Number (which is mandatory and cause me problem)
- Description
- Item Description
- Unit

I manually map them but can't figure how to map the "Reference Number", I ve tried the brute force method by trying every fields without any success : any Idea ?

Thanks and regards,
