Can't submit Expense report due to single itinerary

[oouyang]

I can't submit the report due to this alarm message. 
"This report could not be submitted. This report contains at least one itinerary with a single itinerary row. An itinerary is not valid until it has at least two rows. Please add another row to complete the itinerary." 

My purpose is to report the expense for relocation. That means I only have one-way trip. And all the cost category I choose is "Relocation - other moving costs". 

Please help to figure out the root  cause.

@oouyang as far as my understanding goes, Travel Allowances are for business trips. Relocation wouldn't necessarily fall into this category, so I would recommend speaking with your manager about this. It might be that you don't claim travel allowances, but rather just submit individual meals for your relocation. If that ends up being the case, you could delete the travel itinerary from off the report. This is best answered by someone at your company as it is an unusual scenario. 

Did you drive to your relocation or fly? How many days did it take you to get to your destination?
