Answer 1

ich gelöst, dass mit folgenden Lösung:

1. Added report group to the report 
2. Added new variable with type of string (var_name) 
3. On the variable expression property of the variable, 
    $V{var_name} == null || ${var_name} == "" 
    ? "1" 
    : ${var_name} + ", 1" 
4. Set the reset type of your variable to **Report** and its reset group to the report group you created at step 1 
5. Then on your report layout, edit the text field expression of your id, color group and description to the following 
    $V{var_name} == "1" 
    ? ${field_name} 
    : ""
