Date should appear only once for the personid. But I am getting duplicate record from the database. Date is displaying again and again for the personid.

How to skip the duplicate record. Can any one help to solve this problem.

Answer 1

Hi, i haven't worked for long time with crystal reports but try one of two things First and better is to use some kind Group By or Distinct in your query.Beside solving this problem it also makes the report run faster because it won't render so many duplicated data. Second thing( i am not shure about it ) but i think there was a propraty Suppres Duplicate Best Regards, Iordan

Answer 2

You should be able to group by PersonID and then by Date, move the fields from the details section to the Date group footer and then suppress the Details, PersonID Header and Footer, and Date Header so that the Date Footer works as your details row. Doing this will only show one row for each PersonID and Date combination. Hope that helps.

Edit: Each group header and footer only displays once for each change of the value. Therefore in your example if you didn't suppress any sections you'd have something like the following:

GH1 - 3100
  GH2 - 22-02-2009
      D - 3100   22-02-2009
      D - 3100   22-02-2009
  GF2 - 22-02-2009
  GH2 - 23-02-2009
      D - 3100   23-02-2009
      D - 3100   23-02-2009
      D - 3100   23-02-2009
      D - 3100   23-02-2009
  GF2 - 23-02-2009
GF1 - 3100
GH1 - 3200
  GH2 - 22-02-2009
      D - 3200   22-02-2009
      D - 3200   22-02-2009
      D - 3200   22-02-2009
      D - 3200   22-02-2009
  GF2 - 22-02-2009
  GH2 - 23-02-2009
      D - 3200   23-02-2009
      D - 3200   23-02-2009
      D - 3200   23-02-2009
      D - 3200   23-02-2009
  GF2 - 23-02-2009
GF1 - 3200

Therfore if you hide all of the sections except for the GF2 sections you'd get:

  GF2 - 3100   22-02-2009
  GF2 - 3100   23-02-2009
  GF2 - 3200   22-02-2009
  GF2 - 3200   23-02-2009
