How to develope a KM filter with EP 7.31

Dear all,

I have following questions regarding KM filters on an EP 7.31:

1.)Where the NWDS assistant for this purpose is gone on 7.31? Compare to NWDS 7.0:

2.)Are there any changes in the structure changes in the package between 7 and 7.31? Is this documented somewhere? Are there any tutorials or anything else about that? I found nothing about KM filter development excepting information on configuration, are own filter developments not longer supported on 7.31?

Thanks,

regards
