I have the following lookup code:
=Lookup(Fields!Item_Number.Value,Fields!Item_Number.Value,Fields!Item_Short_Name.Value,"Inventory")
I am getting this error:
The expression used for the calculated field '=Lookup(Fields!Item_Number.Value,Fields!Item_Number.Value,Fields!Item_Short_Name.Value,"Inventory")' includes an aggregate, RowNumber, RunningValue, Previous or lookup function. Aggregate, RowNumber, RunningValue, Previous and lookup functions cannot be used in calculated field
I have no computed or calculated expressions in any of the fields. I have two datasets, Equipment which is bound by the report and Inventory.
Any help where to look would be appreciated.
