Were the settings in Options, Properties for the Units page changed after the fields were inserted?

If they were, you will need to modify the properties on the each individual field to turn off the Variable decimals option and to set the Decimal places field to 0.
Alternatively, remove the fields and re-insert them.

When you are previewing the specification, are you still in the Designer or are you in Adagio Invoices?

Please exit from Adagio Invoices and then go back into the Designer and edit the specification. If the unit fields appear to be formatted correctly, please go to File, Preview and check the alignment specification.

If the fields are not formatted correctly, remove them from the specification and reinsert them now that your Options, Properties settings have been changed. Be careful to remove all unit fields. You may have them in more than one section or you may have one stacked on top of another.

If the fields are formatted correctly on the alignment specification, go to File, Specification Options and make sure that this specification has a unique name.

Now go back into Adagio Invoices and try to preview a sample invoice.

The oe$inv spec is specifically for printing Order Entry documents using the Adagio Invoice designer technology. It is specifically designed with the OE codes, and you are correct that you won't be able to rename it qi$inv, as the format for Adagio Invoice invoices is different.

I did a test, editing the field properties for both quantity and currency fields, and printing the invoice from the main program (not the designer) shows the numbers with no decimals.

Please make sure you are printing with the correct spec. Edit the spec in the Designer, and change the Title from File | Specification Options to something immediately recognizable, so that you can be sure you are using the proper spec when printing invoices.

After doing some research, we found that specifically the D11, D15, D16, D35, and D36 codes in the Order Entry printing does in fact exhibit a problem with not formatting decimals properly. All of the codes printing QI invoices should work OK; that is where the confusion lay.

We will address this issue shortly.
