Accounting setup? Accrual and charge Account

Hi Gurus,

I have a situation where the Accounting is coming to GL from Purchasing, We are using MONTH end Accrual.

When month end accrual is run the accounting is getting sucessfully creadted  All PO accounting is creates accounting as follows

Dr Charge A/C

   Cr AP ACCRUAL a/c

However the PO orders raised for projects have a different accounting and iam not able to figure out where it is being configured to generate accounting as follows

DR  Charge a/c

   CR Charge a/c

Is it Account generator which is generating the accounts for the projects?

Appreciate your help.
