Budget monitoring of asset with statistical internal order

SAP Gurus,

SAP help says that 'in FI-AA we can monitor budgets for assets by posting acquisition directly to assets, while at the same time making a statistical automatic posting to an internal order'

Prerequisites for this are

- acquisition transaction type in asset accounting have to be designated as 'relavant to budget'

Can someone tell me where is this config setting done. How do we make transaction type relavent to budget?

Thanks
