Hi JGAnderson,
Certainly happy to help out! There arent any hard limits imposed on the Generate Report action, so you should theoretically be able to generate as many records in your Report as your Filters will return. Are you getting exactly 100 Records? There is an option on the Generate Report Action called 'Filter Safegard' which will return the first x amount of records;
First up, I would check your Generate Report action to ensure you havent set the filter to only return the first 100 records.
If this is not the case, let me know and we can explore other possible solutions. We might need to try exporting the data with the same filters directly using the Import/Export Tool and seeing if it returns the same results.
Regards,
Ben
