I have a customer who started to use positions for stock. They have run into issues with correctly tracking stock at positions.

I traced the issues and found out that the way it is coded, tracking serial numbers at positions in the warehouse is only possible if cost accounting is set to FIFO per serial number.

Has anyone encountered this problem? Surely, this can't be by design?
Is there any way to get items with serial numbers to properly work with stock positions without tracking cost per serial number?
