When changing customer number in 5.5 for one account i am receiving fallowing error:
"Error changing number/code! Error Code = 127"
That's a problem with case sensitivity, i.e, "123A" versus "123a". Run Rvspy during the conversion, it will probably take data surgery to fix.
Error 127 means duplicate key. Run the RVSPY utility. If it's not the customer number, then it's an invoice number.
