When you close an accounting batch, you are asked if you want the exported file in IIF or CSV. We export to CSV every time since we don't use Quickbooks. Just now, however, our office manager accidentally chose IIF. "No worries," I thought, "we'll just re-download it and choose CSV." No dice.
When you go to Exported Batches and click Download, you are not given the choice of format, it just begins downloading another IIF. To fix it, I went to the civicrm_batch table in the database, found the batch in question and changed its status ID to 2 (Closed). This allowed our office manager to export it again, but in the correct format. (There must be an association somewhere in the database between file format and export batches; I wonder where that is... I digress).
My actual question: What is the best way to prevent choosing the wrong export file format on the batch export screen? Disable the IIF option with CSS and/or JS? Can I prevent the IIF option from even systematically appearing since we don't use it? Where would I adjust that?
