Units for Inventory Volume

(0) ShareShare
ReportReport
Posted on by 190

I desire to track inventory volume in cubic inches instead of cubic meters, and I need to increase the decimal precision from 2 to 3.

I have changed the System Units for the Dry Volume class from cubic meters to cubic inches, and I have made the precision change, but the changes are not reflected in the product details form.

Is this change possible?  Am I missing something?

Thank you,

Chris Italiano

    The volume field on the item master doesn't really have a unit, it is implicit or assumed.

    If you want to increase the number of decimal places just change the format of the field's extended data type.

    Thank you Tim.

    We have done a lot of testing and we found a few other issues with the volume calculation.  Interestingly, units seem to be irrelevant.  Changing the system units for either the Length or Dry Volume class does not have an impact on the actual inventory location consumption.

    Our remaining issue is that the Volume specified on the Product does not impact the consumed volume in the inventory location.  Instead, the location's consumed volume is calculated using the Gross dimensions of the product.  Furthermore, the consumption is not based upon the calculated volume of the location, but instead it is based upon the defined Maximum Volume of the location.  This is where my confusion with the units began - the derived units on the calculated product volume should be the system units for length, cubed; the assumed units on the max. inventory volume should be the system units for the dry volume class.  (I cannot confirm either of these as fact.)  If the system units for length and the system units for dry volume are not both of the same base (imperial or SI), then a conversion must occur as part of the volume consumption calculation.  But based on our testing, no conversion is occuring because AX seems to be ignoring the system units.

    Since this is all now well understood, we can move forward, but it does not match what the function described in field's help.

    There is one more strange behavior related to volume that we need to resolve: the defined Volume of the product is not propagated to the Volume field in the WMSOrderTrans table.  We desire to know the volume of the items we are going to pick.  We are going to test the Gross dimensions further so see if this resolves the problem.

    Thank you for your reply.

    Sincerely,

    Chris Italiano

    Well, it was a short experiment... no luck.  We assigned Gross dimensions to a product, then created a pick list for a shipment, but the Volume field in the WMSOrderTrans table remained at zero.  I will post a follow-up question.

    In our business process we have to calculate the chargeable weight for both the inbound and outbound shipments.  Calculating Chargeable weight is as follows:

    Calculating chargeable weight:

    Volume = (length x width x height)                                                                                                                                                 

    The Volumetric weight calculation varies based on the type of the transport.  

    Volumetric weight for Air - (length x width x height) / 6000 - Cubic Centimeters per Kg

    Volumetric weight for Courier -(length x width x height) / 5000 - Cubic Centimeters per Kg

    Volumetric weight for Road (Also referred as Economy) -(length x width x height) / 5000 or 6000 – Only for customer it is 6000 and for all others it is 5000 -- Cubic Centimeters per Kg                                                

    For Air, Courier and Road -  Gross weight compared with Volumetric weight, Which one is higher we will consider it as Chargeable weight                                                                                                                              -Volumetric weight for Sea - (length x width x height) - Cubic Meters per Ton or Cubic meters per kg (For Sea we will not compare  Volumetric weight with gross weight. we will consider volumetric weight as the  chargeable weight)

    Please guide us how to implement this in WMS / TMS
