What this error message means, and what to do if it pops up:
The maximum number of lines the interface will process is 32,000. This is all inclusive of all files within the Import Folder defined in the source configuration. The file name listed in the message box is the file it stopped processing on. This file will not be imported, and potentially other files as well. For an explanation of source configuration see the article Configuration - Source Configuration.
NOTE: A file containing more than 32,000 lines will need to be broken down into multiple files with less than 32,000 lines in each file. If one file has a header row, and that is what the source is configured for, then all files must contain that header row. The header row is not needed by the interface so it can be removed, remember to uncheck the option Header Row Exists in Source Configuration.
If Delete source files after they are imported option in Source Configuration is checked (as shown below); the interface processed what it could and removed those files from the Import Folder. If you rerun the interface, it will pick up on the file it left off at and continue processing until it finishes or reaches the limit again.
If Delete source files after they are imported option in Source Configuration is NOT checked; change the verbosity level under Advanced Configuration to at least 3 or a higher number, and rerun the interface.
The lines starting with Processed: will contain the files that were imported. Move these files out of the Import Folder and rerun the interface.
