Some people like to just get in there and start putting the bike together, straight out of the box, without just taking a moment to read the instructions or user guide first... and good on them I say! In fact, more often than not, I am guilty as charged - and the same goes for new online tools. That's why we have tried to make the Group Booking module as easy as possible for first time users.
The booking process on the tool itself is proving to be really straight forward and easy to use, but case studies so far are suggesting that populating the import file with accurate booking request data in the right format has not been so clear - yet it is probably the most important part in making sure Group Booking works as expected.
So while there is plenty of information in the release note on how to get it right, the latest Group Booking version that has just been released includes a new rejigged sample file that is available on the setup screen for use as a starting template, to make it easier to understand and more foolproof for beginners.This includes some more validation and input messages, and removing some columns that were created at the start of the project but are no longer required (for now at least anyway).
Make sure your version of Serko Online Group Booking is up to date to download the new sample file.
