The sales price U/M is key to the behavior in the customer order process. If the sales price U/M is:

The same as the item’s catch weight U/M, the quantity in the sales price U/M is equal to the reported catch weight.

Not the same as the item’s catch weight U/M, then a conversion must be performed.

Defined to be a CW price U/M in 'Item. Connect Alternate U/M' (MMS015), then the reported catch weight is converted into a quantity in the sales price U/M.

Not defined to be a CW price U/M in (MMS015), then the quantity in the basic U/M is converted into a quantity in the sales
price U/M.
Example

Item’s basic U/M = PCE (0 decimals)

Item’s 'Std CW U/M' = KG, with conversion rate 1 PCE = 2.000 KG (3 decimals)

U/M 'LB' is defined as a CW price U/M with the conversion rate 1 PCE = 4.40924 LB (LB has 3 decimals)

U/M 'KGF' (with fixed conversion rate) is defined as a normal sales price U/M with the conversion rate 1 PCE = 2.000 KG (KGF
has 3 decimals)

Quantity in basic U/M = 5 PCE and the reported catch weight = 9.800 KG

Quantity in the different sales price U/Ms would be calculated as below:

KG: Sales price quantity = 9.800 KG

LB: Sales price quantity = 9.800 KG/2 = 4.9 PCE = 4.9 * 4.40924 LB = 21.605 LB

KGF: Sales price quantity = 5 PCE * 2.000 = 10.000 KGF
