I am preparing a SSRS report where a table in the body has to be generated by considering a field value in header part and should repeat the same for all values of that field. I have created a group in body and used the expression =First(Fields!Field.Value, "DataSet"). It is generating all the values in the table but value in the header part doesn't change.
I also tried creating a group in the table and using one of the value from the group in the header part. But it is not possible as we are restricted to use group variables inside the group but not in the header part of the report.
