F110 downpayment request error for document splitting

hi, experts:

While I try to post for vendor downpayment request in F110, it pop up error message as "Balancing field "Profit Center" in line item 003 not filled", I have test, if only one downpayment request, it can work in F110. But for multiple lines, it generate such message.

If I maintain default profit center in FAGL3KEH, it can work there, but I think there should be better solution.

could you please give some advice?

Thanks
