Solution 1

Yes, it can be done.

Option 1:
At QUERY level: Make a query that returns the data as you showed here

Option 2:
At REPORT level: Do a grouping by ID in your report.

Try!

I have searched and tried this formula but it did not work correctly

Group Header section)
shared stringvar b;
b := '';

(Detail section)
whileprintingrecords;
shared stringvar b;
if not IsNull({DaySheetReport;1.Code}) then
(
if (b = '') then
b := b + {DaySheetReport;1.Code}
else
b := b + ', ' + {DaySheetReport;1.Code}
)

(Group Footer section)
shared stringvar b;
b

it shows the data like this

1 A
1 A,C
1 A,C,F
2 C
2 C,B

What is the problem with the code?
