The Purchase Order expense in not effecting in GL accounts

When a PO & Invoice is raised and payment is made in Accounts Payable, but presently the highlighted in italics cannot be seen in the GL.

RAISING OF PURCHASE ORDER

· Credit: Supplier/Vendor

RAISING OF INVOICE

WHEN PAYMENT IS MADE

· Debit: Trade Creditors

We have noticed that when a purchase order has been raised, we do not see this expense head in General Ledger section (click on REPORTS ----Ledger transaction list).
For example:
Vendor Name – SAKTHI AUTO WORKS
Purchase order – 000344
Vendor Account – BGHO 000048
Description – Car Repair
Amount – Rs. 46, 000

All the PO transactions for this vendor cannot be found when we search within the GL (expense head).

Please Help me .

Gokul.

There is no financial transaction at the point of raising. Only are receipt when you have received something and there is a liability.
