EWM - Waves not created automatically

Hello All,

I have a big Doubt with EWM, I need that system creates the waves automatically and I complete the Wave templates in the tcode: /SCWM/WAVETEMP, then I went to the Other Tcode: /SCWM/WDGCM, But something is Missing because the system doesn't create the waves automatically, I was doing sombe research in the web, but I can't find what's missing.
