Niraj,
To achieve the report requirement i.e., for example -X object details by employee id or employee name,I will put the below condition only in where .
Employee table. Employee ID IN @prompt('Select one or multiple values for Employee ID:','A',’Employee table\employee ID’,Multi,Free,Not_Persistent,,User:0,optional)
AND
Employee table. Employee name IN @prompt('Select one or multiple values for Employee name:','A','Employee table. Employee name', Multi,Free, Not_Persistent,,User:1,optional)
Is this correct?
