I can't see anything obviously wrong with the logic.
What I would do next is put two textboxes on the report, one for
=(
iif(Sum(Fields!TotalInvPrimaryPart.Value, "PartNumber")=0
,Sum(Fields!TotalInv.Value, "PartNumber")+first(Fields!TotalInvPrim.Value, "PartNumber")
,Sum(Fields!TotalInv.Value, "PartNumber"))
+
iif(Sum(Fields!QTYonOrderPrimaryPart.Value, "PartNumber")=0
,Sum(Fields!TotalQTYonOrder.Value, "PartNumber")+first(Fields!QTYonOrderPrim.Value, "PartNumber")
,Sum(Fields!TotalQTYonOrder.Value, "PartNumber"))
+
iif(Sum(Fields!QTYonPMRPrimaryPart.Value, "PartNumber")=0
,Sum(Fields!TotalQTYonPMR.Value, "PartNumber")+first(Fields!QTYonPMRPrim.Value, "PartNumber")
,Sum(Fields!TotalQTYonPMR.Value, "PartNumber"))
)
and one for
= iif(Sum(Fields!AvgMonthDemand12PrimaryPart.Value, "PartNumber")=0
,Sum(Fields!TotalAvgMonthDemand12.Value, "PartNumber")+first(Fields!AvgMonthDemand12Prim.Value, "PartNumber")
,Sum(Fields!TotalAvgMonthDemand12.Value, "PartNumber"))
Just to check they are returning the correct values.
