Troubleshooting

In case an error is detected and displays the text *SOURCEPOSITION*, you can open the function by double-clicking or by executing the command Show source code in editor from the contextual menu. The cursor marks the relevant position. You can also use the project archive including the Download information files and the exported log file for diagnostics. In case of protected functions, the message The source code is not available for <function name> is displayed.
