What does code po732 mean on 2001 BMW 750iL

It's a generic" incorrect gear ratio" code, indicates a transmission problem.
You really need to get a BMW specialty shop diagnose this condition with an OE diag. computer to have a more factory specific diag. trouble code, regular OBDII readers are not capable to read those.
