This error means that there was an issue parsing your dataset files. Either there is something wrong with your files, or there is a problem with our source file parser. Can you please let us know what source type you’re using (probably SAS XPORT), as well as the Validator version you ran the validation with?
You can determine what version of the Validator you’re running by going to Help → About OpenCDISC Validator in the desktop client.
After we ran the checks, we received few Parsing Errors with the message ‘error parsing source’ with the category as System. We received these errors for different domains and we were not able to understand what is the meaning behind this, how to understand and resolve it. Any information, help is very much appreciated. Thanks.
