I would give these explicit Pin Numbers (e.g. 1, 2, 3, 4, 5, 6) in Cell Editor rather than alpha characters. By specifying the Pin Numbers as 'A' and 'C' you are not giving the tool information as to what should be the first pin. In other words, I'd have the cell look like this:
You can then short those pins in the schematic, or by defining a Signal or Supply Name within the part's Pin Mapping:
There is a way to set Pin #1 within the ODB++ data through Valor NPI - within Graphic Station you can navigate to Component > Set Pin #1. I've attached a screenshot of that below:
However, I'm hesitant to recommend that because you're fixing the generated data rather than the underlying cause (the faulty cell).
I might go one better to avoid PIN number confusion since this is a polarized component.
C1 to C3
And A4 to A6
I like to keep the C and A on diode components.

Thanks for your reply Vern,
as far as I understand the Cell Editor logic, it just picks the first pin in Alphabetical/Numerical order. So with your suggestion, everything stays the same for me as A4 comes before C1 (which must be pin1). The only chance is to call the pins 1C to 3C and 4A to 6A to get the right sort order for ODB++
But the disadvantage is that our developers see "different" diode symbols in the schematic (e.g. a part with two pins (1 anode, 1 cathode) has an other symbol than a part with six pins (2 anodes, 4 cathodes)) although it is irrelevant for them because they just want to use a diode.
thanks for your answer.
The reason we use the method to short the pins by pinname in the library is because we use only one two pin symbol for all diodes in the DxD schematics. This is done for easy replacing on schematic layer, to reduce symbol variants in library manager and to eliminate confusion for our developers (a diode is a diode no matter how many pins it has). If I use pin numbers 1 to 6 I have to assign a symbol with 6 pins on it - right?
As far as I know the Supply Name only assign an implicit supply to pins, e.g. GND to 1, 2, 5, 6. This seems not related to my problem as I want to assing 4 part pins to 1 expicit schematic pin (the cathode) for example. The Supply Pins never appear on the symbol or in the schematic.
