Hi,
I got this requirement from the client.
Receive the items with serial numbers, but have the items reserved on sales order lines on site and warehouse level only.
I tried setting up this one with the following storage dimension group setup:

And then here's my tracking dimension setup:

With the above setup I can receive PO lines with serial numbers.
Issue is when I create a sales order line, since we have auto-reservation the system reserves up to the serial number level.
Thus when generating a picking list the serial numbers are already defined, which we know is very hard for warehouse workers to execute if it happens that the serial number reserved is not easy to reach inside the warehouse.
We wanted that only the site and warehouse will be reserved and by the time we pick the inventory from the warehouse that is the time that we define it in the pick list.
Regards,
RIEL
