When entering any expense GL I can put data in cost center but not in WBS . If I will change the FSG of this Expense GL and make wbs optional or mandatory I can then put data in WBS . But I want to know without putting Data in wbs for expense GL can I get any report of this exp.GL from wbs reprot like S_ALR_87013545. How configuration should done between PS and FI so that we can get wbs report for expense GL .I am new to this controlling part. So please guide or suggest.
