I know the question has already been posted, and answers where given ; I read this topic ; Of course I can try to insert the sObject and get the error listing the missing fields,
But isn't it a 'better' way to do it ?
I'm pretty sure I had found a way, but can't find it anymore ;
At this moment my favorite option remains to use the Schema Builder in wich it's obvious (red lines in front of each required attribute) -->
But isn't it a way to show a column required / not required, in the object manager ? -->
Same question, in the dev console ? -->
Thanks for your help !
