Hope you are keeping well. - I found this trend and it had helps a lot with what I need to do… The main part of this is adding a Field to an SSRS report…
I have followed this and have come to a problem, when I when to Sync the Dataset, I got the below error.
Personalize Report Style and never again hit “that” button we do not speak of…
LoL, kidding aside, the prescribed methodology for adding the field is to make the change to the RDD and then manually make the change to the Dataset query expression that is inside the RDL using Report Builder.
EDIT: Come to think of it, why is your Data Definition not populated?
