Hi Vadivel,
It is simple because string is allowed subscripting ([ ]) in python. So, according to that your requirement will be fulfill as like below.
As your field named "desc" will take 50 characters and you want print only 20 in report. Just make this line inside your report, requirement will fulfill.
1) object.desc[0:20] #It will only takes 20 character from desc field.
2) object.desc if len(object.desc) < 20 else "%s..." %(object.desc[0:18]) I hope you will get what you want.
Thanks.
