I would like export multiple files and as separate records, but when it joins single with multiple records some sections are wrong. The message displayed is related to Internal Error. Is there any solution?
An internal error means that the software has issues with that function/module or the data that you have is not correctly added into the application. I've opened the complete user guide and it appears that there are additional ways to export the data and each function has a different data.
