Problem in executing report in background in CS workflow

Hi All,

I am using ECC 6.0 version.

In my scenario , Once notification is closed , workflow should trigger. and along with this , one report should execute in background with input parameter as a Notification no. from workflow . Report should pick up input parameter dynamically.As I know instead of function module we can choose report option in business object .

My question is how that report will get input parameter as notification no.& How I do the binding for this (Between report & workflow)?

Valuable suggestions are excepted.

Regards,

Sheetal
