Can't buy an asset as described in the manual

Could anyone tell me what I did wrong?

  1. I created an Asset Category

  2. I created the only Item master with Asset Category

  3. When entering an invoice, the wrong G/L appears.

the problem that even the item is Asset it take the account from the Item group and not from the Asset category …
easy way out is to select the expense account in item inside Purchase section and set the asset desired account

Thanks ahmad

What I wanted is like below.

When receiving, CWIP appears
Then reverse CWIP, aquire new asset against it
