Hello again, i missed the opportunity to give a feedback on this.
I used excel capabilities to sort out a list of the designator and on the next column their manufacturer ref.
I then extracted the list of designator from the parameters manager to excel where i matched the Manufacturer ref to the designator in the same order. copying back to altium the manufacturer part ref list into the parameter manager (and then ECO of course).
In case anyone fall into the same kind of trouble somedays
, please find attached an "example" of my sorting algorythm for excel. I did it in the extend of my knowledge and thus it might not be optimized (if you use it and something goes wrong, i won't be responsible).
red columns: my input data
orange columns: various sub-step data
green columns: outputed data
thank you again for all your previous answers, they helped me.
