Many L2L Customers routinely perform minor dataloads on their own. When uploading data into L2L via Import Tool, it's tempting to use a saved Table Mapping Field Template that has successfully uploaded data for you previously. After all, you nurtured this template from nothing and you hate to part ways now. We understand.
However, at some point, you are going to wonder what happened? You've used this template many times and it has never let you down. Suddenly, mysterious error messages appear, seemingly out of nowhere. And no data has been uploaded. Where is your faithful friend, the Saved Table Mapping Field Template?
So, your friend STMFT had a tune-up and you're the last to know about it.
The best practice is to always start with a brand spanking NEW Table Mapping Field! You can save a previous Template for reference, but start with a clean slate! You'll save yourself time, head scratching, and aggravation!
