Accounting Entries for Purchase Order Work Order Destination

Hi,

We are facing a problem about the purchasing processs from maintenence. We have some items that are purchased to be applied on the work orders. We create some purchased orders and all the process were generated (Receiving and Invoice Validated) and the only accounting entry generated was the invoice validated event.

We have a question, how the accounting entries are generated for this process and which accounting classes are used for that.

For example:

Payables: D - Accrual
C - Liability
