Auto-maintenance method

Hi,

Here is my requirement. The credit item should be applied to the debit item when all the three contract ID, customer ID and open balance on the credit item matches with that of the debit item. When I looked at the Automatic maintenance method, I can see that only one mach reference can be selected at a time for each step. How can this requirement be fulfilled? Is it possible only with the new algorithm.

Any thoughts are appreciated.

Thanks,
