Not able to bind infotable output as input to event router

I'm trying to use event router to channel two output into one. One is coming from grid's edited table and one coming from service1 . while creating the event router I have selected the same datashape for the service1 and the output of service which is passing data to grid. still when I try to bind grid edited table to event router it gives error as both router input and grid edited table need same datashape.
