The customer is using the budgeting with encumbrance at PO level, due to this funds check is failing for tax amount as tax budget is booked against the tax account combination but, invalid account combination defaults from Item charge account at PO level.

Please suggest - is there a way to populate Tax account combination from tax configuration instead of the charge account at PO level?
