Hi Experts ,
The issue is related to Downpayments .
When we make downpayments against the Purchase order account assigned to WBS element in the Tcode F-48 system is not consuming the budget which is assisgned to the WBS element .
Neither the Values are shown as actuals in 87013558 Report .
The settings for AVAC is catered for all business process that is ++ and no costelements are exempted .

Appreciate if some one could help....
