HI!
I have large model made in ModelBuilder in ArcMap. First step is to create GDB where all of the outputs are saved. I need to the final output save in another output location. So I add "if data exists" this final output and I connect Yes (like precondition) with Delete that GDB. But it does not work.
When I run just Delete GDB - it works, but with those "if..." not.
What is the problem?
I know about scratch workspaces or in memory, but I need it this way in case it crash..
