I have a dataset which brings in distinct values of a column 'A' of table 'B' and these form the select values for a parameter 'Param_A'. In addition to this I have a main dataset which brings in data from table 'B' and contains the column 'A' as 'Field_A'.I do not want to alter the main dataset and hence I am using a tablix filter to filter out the result set of the main dataset. The tablix filter is supposed to be performing the below functionality :
Expression: Fields!Field_A.value in (Parameter!Param_A.value) or Fields!Field_A.value is NUll
Boolean Operator : "="
Value: True
But I am unable to use the operator 'in'. It gives me an error.Could you please help me out with this?
