FICA to FSCM Credit Management integration without using PI (using WS-RM)

Hi ,

We are implementing FSCM credit managment to integrate with FICA. We configured credit management related settings on both sides but we have some questions regarding integration:

1. Without using PI using WS-RM how can we integrate? Please provide any documentation or config guide for integration and also how to send data from FICA to FSCM
2. What all interfaces are required if we have to provide key figures Dunning, Returns and Write Offs data of a business partner? Any guide or documentation on how to trigger the interface to enable data transfer

Thanks,

Suresh
