Here are the immediate issues I encountered while checking the POS on demo.erpnext.com
There is a submitted transaction blocking the queue (not getting synced). The system was throwing up an error report which was subsequently forwarded to support. I however noticed that the customer for that particular sale did not exist (probably deleted before the sale could sync) so I went ahead to create a new customer with the same name. This resolved the first issue
After creating the customer, the error report stopped popping up but now there’s an error message that says ‘Due Date can not be before Posting Date’. The transaction is therefore still not getting synced and holding up the queue
The numeric keypad for the cart sometimes doesn’t load. Whenever this happens, a refresh is needed to bring it back
For the first issue, the system should have displayed an error message like ‘Customer Not Found!’ or ‘Customer Does Not Exist!’
There should be a way to grant permission to certain categories of users to be able to delete submitted orders from the queue. This will come in handy for special situations like this so that transactions don’t get held up until a bug-fix arrives!
Please look into the issue of the keypad not loading from time to time
Thanks for the awesome job you’re doing
