After server scripting feature, is it possible to set default value of item qty on sales invoice to zero or blank instead of 1.
That’s a great question. No, I do not think it’s possible, using server-side code.
I recently investigated this. I was hoping to discover a initial_values() or default_values() Python hook I could use. Something that would change the defaults, under specific circumstances.
However, I found nothing like this.
This would be an excellent feature, though.
