I just found out I cannot do a nested lookup but how do I display a value from a 3rd dataset based on of my 1st lookup expression between dataset#1 & 2? For example:
The tablix1 is based on Dataset1. In Tablix1 I have a column with the following lookup expression:
=Lookup(Fields!WorkID.Value, Fields!WorkID.Value, Fields!AssignedToID.Value, "Dataset2")
Result AssignedToID: 1234
Now, what I want to do is to include the name of the staff with the AssignedToID 1234. The staff name is part of the Dataset3. Dataset3 has the following fields:
InternalUserID = this is the same as the AssignedToID
FirstName
LastName
I tried creating a calculated field in Dataset1 to get the value of AssignedToID from Dataset2 so I could use the lookup from Dataset1 to Dataset3 but it says I cannot use lookup in calculated field.
Any help is greatly appreciated. Thank you,
