how to connection on the connector has multiple solder pins with same pin number, it is NOT required to have multiple pins on the schematic?
You don't say what version of software you are using.
We are on the Dxd/Expedition flow and it is very easy to setup what you are asking, if I have understood correctly.
Within the cell editor we create our footprint with 16 pins, but number them 1-8 twice (so we have 2 x pin 1, 2 x pin 2 etc)
Then in the pdb mapping we have an 8 way schematic symbol which maps pin 1 to pin 1.
From the scheamtic point of view the symbol has only 8 pins, but from the footprint point of view there are 16 pins.
This is only one example.
We could have a connector symbol in the schematic with 1 pin, but the footprint has 20 pins (each one would be called pin 1) and everything maps fine.
