Hello,
when I create customer shipment entry, I got the following error. First I thought it could be a BPM. but I checked there is no BPM related to the pkg weight x height x width.
can anyone tell me where to set up this validation. pkg W x H x W must have value. there is no customization involved. I tested as base mode.
You have most probably selected a packaging code in the shipment, which does not have dimensions setup. Setup the dimensions in MatMgt>Shipping Receiving>Setup>Package Code
EDIT: If the package code is set to Prompt you should enter the values in the Shipment, in your screenshot behind the error box I can see the dimensions are 0.
If the package code is set to Set Value, I believe the values are copied to the Shipment and fields are disabled.
