Any warnings? It can be that there's some attributes which are not the right type for the schema in SDE. E.g maybe a sting going into an int column

Hello @arthy​, joining the conversation a little late, apologies! If it indeed is a schema mismatch issue, you could use '+ > Import from dataset' to grab schema of an existing table. However, I notice you used an attribute value to define the table/featureclass name, so I am unsure Import will work in this case! Hope this helps, Kailin!
