Hi All, I faced this issue "You must enter at least one line item for this transaction" when transform from sales order to item fulfillment with suitescript 2.0 aftersubmit method. Any advise ?

Are there items to be fulfilled on that SO and have you applied them on each line you want applying on the IF? (presuming your account is not set to auto apply all lines)

@NElliott Yes there is items in SO lines and I applied it to each line

Did you set a location? Are you using multiple-locations

the usual answer is to fulfill the sales order in the ui and pay attention to the url while creating the fulfillment
