If auto(magical)correlation does not work then use manual correlation.
Record twice with same data: Compare. You will find session, state and time data.
Change the credentials: Re-record. Compare. You will find credential related correlation
Change the business record but keep the same business process. Re-Record. You will find the business related correlation.
Do not expect autocorrelation to provide a magical working script. You have about a 0.0001% chance of that happening without LoadRunner script development intervenetion.
