Customizations to Locbox program in SAP

Hi,

Could anyone please tell me some customizations you have done to Lockbox program.

specifically for your project needs, the reason why you did it, how you did & how it improved you matching rate of customer invoices or clearing etc.

the reason why I am asking this question is because we have implemented the standard lockbox functionality for our client, it is working pretty fine but the client is not satisfied with the match rate he is getting for clearing customer invoices.

you could give any possible suggestion apart from the standard lockbox functionality you have implemented not only just for match rate.

Thanks in advance.
