If you swap pins in Allegro, like pin a and b in following picture (Before).
And after back annotate, Orcad exchange A and B (After).
Can we make any configuration to make the back annotate results like (Need) ?
No, not possible. The reason the pins were swappable was that they were "identical". If you have swapped pins that are not identical then this becomes a "function" swap. That gets more complicated and is not supported under a single graphic as you show.
If you want to reannotate after swapping I recommend editing the symbol in Orcad after the swap and using Excel to move the pins around back to the way they were. :)
In reply to redwire:
Can you explain more details about the reannotation you mentioned above?
