Where to add expense cost to system

how can I add cost in Indirect Expenses account
Thanks

@Wilson_Wang
currently only way is via journal entry
this ERP lacks in this regard,for now, other accounting software have option to enter purchase invoice linked to their respective expense Account e.g, rent, utility expenses, advertisement expense,

here we have to create new item every time

  1. create a new item as service item,
  2. Assign it to respective expense account
  3. and then enter invoice linked with that supplier
