Business Validation Error: your purchase order date needs to come before all expenses, bills or checks QBO

Hi, Our product syncs users purchase orders with quickbooks. Doing so, we are getting following api error: 

{"Fault"=>{"Error"=>[{"Message"=>"A business validation error has occurred while processing your request", "Detail"=>"Business Validation Error: Your purchase order date needs to come before all related expenses, bills, or checks.", "code"=>"6000", "element"=>""}], "type"=>"ValidationFault"}, "time"=>"2022-08-24T04:57:32.223-07:00"}

Have any one ever got into above error? How does this error gets triggered?

Thanks in advance.
