Withholding tax for TH

Hi,

I've maintained the withholding tax setting for Thailand company, and the withholding tax posting and amount are generated without problem, and the reference3 field is able to contain the document number, however when I generate the generic withholding tax reporting (RFIDYYWT), it got no document selected.

Does anyone has experience of setting up TH withholding tax? or facing this kind of problem before?
