Our Product Deployment team implements tools that execute Progress Open Edge code from .net applications and command line or batch scripts.
Open Edge Error Codes are usually appended to the errors encountered during execution of those code components.
The Open Edge Error Codes that are displayed in the () in the error prompts, are actually windows error codes.
Example 1: Errno 2 — is an access denied error that happens frequently in Windows Environments, those are permission errors encountered on specific paths.
Example 2: Errno 11002 — is an unknown network path error that happens when UNC paths are not resolving properly during the script executions.
