Error: Account number for transaction type Purchase expenditure for expense does not exist

Pada saat posting invoice purchase order ada error : Account number for transaction type Purchase expenditure for expense does not exist

Ini karena COA : Purchase expenditure belum di isi.

Klik kanan view detail product itemnya -> Cari Manage Cost -> Lihat Item Group -> Klik kanan view detail item groupnya -> Purchase Order dan isikan main account untuk Purchase expenditure -> Coba di posting lagi invoicenya
