I am building a terrain dataset and I am trying to run feature class to feature class for a multipoint feature class from a file geodatabase into the feature dataset I created in SDE but I keep getting error 000224: Cannot insert features? The multipoint feature class has just under 4 million points and I was able to load it into a file geodatabase and then successfully run create terrain on my local machine but this error keep popping up when I try to load the data into an SDE database. I double checked and the coordinate systems are the same for the multipoint feature class and the SDE feature dataset.
I am sure there is something I am forgetting to check, does anyone have any ideas? I have attached a screen shot of my tool window and a text file showing the results window errors. I am attempting all this using ArcMap and ArcCatalog 10.3.1.
