Hi,There:

Here is my result table in the preview of DataSet
===================
| Name | Group |
===================
Clark Admin
Clark Financial
Clark Staff
John Staff
John Engineer

The requirement is to generate report as blow table, combine all group into one cell.
===================
| Name | Group |
===================
Clark Admin, Financial, Staff
John Staff,Engineer

Could anyone help me what is the best way to do in the report design?

Absolutely. Just add a group on Name and in the group footer use an
aggregation element with the concatenate function. Look at the attached
example. Note that I used a visibility expression to hide all rows
except the group footer. I could have just deleted them instead.

OH,Becuase of limitation of system software, I have to use old BIRT v2.2 only to generation my customized report!

Today, I migrate the report to BIRT v2.2 and found there is NO "concatenate" function in Aggregation

Any one could help ?

The concatenate function was not available in 2.2. You will need to do some scripting. I am attaching an example that shows how to do it using your data. Look at the group header oncreate, and the detail row's group data item oncreate and the expression for the data item in the group footer. Also note that the detail row is hidden using visibility.

Hi Jason

Your sample is work. However, I encounter error at the beginning of deployment of your code. It seems that you edit XML code directly instead of by Layout and Script to define your code.

Finally, I have a table which contains Group by AccountID
For example:
Group Headers | ID | Groups |
Detail | | GrupName |
Group Footers => AccountID | AggredGroupName |

1. Define grpstr=""; in the "on Prepare" of Script of Group Headers
2. Define Groupname fx() as your code
2-1. Define "oncreate" as your code (grpstr += this.getValue() + ",";)
3. Define AggredGroupName fx() as your code (AggredGroupName = grpstr + row["GroupName"])
3. Define grpstr="" in the "on render" of Script of GroupFooters;

The above code is ok and compatible in the v2.2

Otherwise , I will get error result as below:
1. The return value of AggredGroupName is dirty which means contains last one value of grpstr;
2. The end of report will show "grpstr" is not defined when i run the preview.

I don't know the way i do is correct or not ...please advise if any!

Thanks!

I did not modify the xml directly. I used the 2.2.2 designer. I think your method is ok with the exception of this line:
1. Define grpstr=""; in the "on Prepare" of Script of Group Headers

I would do this in the oncreate of the header row as onPrepare is only called once. The oncreate will be called for each new group header row.
