Hi Experts, I always end to up messing my data model and getting wrong result and not sure where to start troubleshooting it. Say, When i change data model for a new requirement and the UI objects shows wrong result, then it means i have done something wrong. My question is from where i can start troubleshooting this kind of modelling issue. I saw developers put some listboxes and do association check, but not sure series of steps i can follow Please guide.
