When building a mapping it is important to have unique field names so if you upload a revised file Smartsheet will find the fields and automatically remap them. Works great. However, when I use the prepare form function in Acrobat to create all my fields, Smartsheet changes the field names when I upload the document to the generator and most of them are not unique so revising the files and uploading them will not result in an automatic remapping. It's important because I have over 300 fields. If I create the fields in InDesign first and then export to PDF, the field names remain unchanged when uploading to Smartsheet, this is good, but I'd prefer to use Acrobat to Prepare Form and create the fields because it's much faster.
