This error is a catch-all warning. It means the Tecdoc data importer (often a custom script, a middleware tool like TecCom, or an ERP module) attempted to read the source data but hit a wall defined by the parameters in your configuration file.
Just before dialing, he opened the configuration file one more time. At the very bottom, someone—probably the previous IT guy—had left a commented line in Spanish: ; Recuerda: los datos no fallan, solo las rutas que olvidamos. ( Remember: data never fails, only the paths we forget. )

| Practice | Why It Helps | |----------|---------------| | | Save your configuration file before any TecDoc update. | | Document changes | Keep a changelog – who edited the config, when, and why. | | Use environment variables | Avoid hardcoding paths or credentials; use %TECDOC_DATA% instead. | | Monitor disk space | If the data drive fills up, loading will fail mid-process. | | Test updates on a sandbox | Always validate a new catalogue release on a test PC first. | | Set file to read-only | After a working configuration is verified, mark it read-only to prevent accidental edits. |
