This is a common error message that can occur on mainframe computers. S0C7 is an error that means you had a check exception while your job was executing. Most often this error occurs because of spaces being moved into a packed decimal field. It can also occur if you move this to a numeric field. Somewhere you are mismatching data that is causing this to crash, you can also go through your job dump to find the exact line causing the crash to determine where in your code this needs to be corrected. This error should never occur in production, as this often can occur in test while your mainframe code is being tested for the first time.
