Your site utilizes the L2L Production Module
You use Product Orders
You utilize eKanban Cards
You are currently running a Product Order
Where are the eKanban Cards? For some reason, you are not seeing the number of eKanban Cards / Product Orders you expected to see in the eKanban Queue.
Please do not panic. Calmly go to your computer. Walk, don't run.
Go to Production > Settings
See how many Product Orders and how many Days to Look Ahead are configured for your site. This may very likely hold the answer to this question if the next order will not start for say, 5 days, and your Number of Days to Look Ahead is set to 3.
Ah. There you go! Well done!
