ECM with iPPE is not reflected to the PP/DS side

Hi all,

We are working on a project with iPPE and we just implemented ECC. We created an integration model for change numbers through CFM1 and activated it through CFM2. The problem is we still can't see the materials with change number on PP/DS side. We deleted iPPE structure and recreated it multiple times after the integration model but it still didn't work. You can see the screen shots down below for a detailed explanation. Can anyone shed some light on this? Any help would be appreciated
