Call FOP and pass BP or CA value from CRM 7.0

Hi Experts,

                  I am trying to call a FOP in ISU system via transaction launcher from CRM 7.0  and also want to pass the value like BP/ Contract Account/  etc. to the FOP during the call. I have successfully one FOP but need to pass the values as well.

Please let me know the steps for the same. Please provide any documents or links with info for passing values in FOP for CRM 7.0.

Thanks and Regards,
