Mixing parcels is straightforward.

You can either manually enter stock numbers you want to mix, either preselect in
Stock Random Selection, which gives you
the option to edit data and then send it to this
mixing utility.

When you click
Save then all parcels are amalgamated into on single new stock number. The form of this new number is
then prompted in order to allow further
processing or editing.
The screen shots hereunder display the results of mixes of a given stock number, bpth in rough and polished.

The lower part can be exported to an external file or sent to the
Stock Random Selection screen for further processing.
The entire mix can be canceled as long as the mix itself is in stock.
