We execute S_ALR_87013611 (Cost center actual/plan/variance report) for a particular cost center and it returns the report. We double-click on one of the cost elements and a pop-up appears. We select 'cost centers actual line items' (KSB1) and when it comes back, ALL cost centers are being reported. When we run just KSB1 for a particular cost center it works fine. This is something that seems to have just started occuring. We've made no security/obj auth changes recently. What could be happening?
