Capacity balancing - Dunning by collection strategy

Hi Experts,

We have a requirement to implement capacity balancing. I have some basic idea around this config. But does anyone have detailed documentation around this capacity balancing in SAP FICA. (transaction FPCMCAP).

Also I want to know how to handle dunning notices that will need to be released manually or by scheduling FPM3_RELEASE.

Thanks,

Suhas.
