Most efficient way of checking for contract changes

Hi there,

I need to extract all the contract changes for certain period of time, and output them into a file. The question is, what is the most efficient way of extracting these changes to contracts?

I know CDHRD / CDPOS is a possible way but it will definitely take a long time considering the way it is structured.

Has anyone out there has a more efficient solution?

Thanks in advance.

Cheers,

Jared.
