Crystal Report: How can i merge and split rows in details section - crystal-reports

Question

Hi i am new to stack overflow, and I am having a problem in crystal report.
Thank you in advance
I am getting output from database like
Name Qty Rate Amount
Mango ice cream 1 100 100
Chocobar 1 150 150
Zulubar 1 50 50
Chocolate cone 1 50 50
Kulfi 1 100 100
ABC 1 100 100
XYZ 1 50 50
Total:- 600
Now what I want to do is merge first three raw and split on 3rd raw.
I want the output to look like this
Name Amount
Mango ice creame, Chocobar, Zulubar 300
Chocolate cone, Kulfi, ABC 250
XYZ 50
Total:- 600
How can I do this?

Answer 1

Assuming your requirement is static and no dynamic is involved. Follow below process:
Create 3 detail sections, detailA, detail B and detail C
Create a formula #First place it in detail A.
Local Numbervar var_Mango_ice_creame;
Local Numbervar var_Chocobar;
Local Numbervar var_Zulubar;
Shared Numbervar total;
if Name='Mango ice creame'
then var_Mango_ice_creame:= Amount;
if Name='Chocobar'
then var_Chocobar:= Amount;
if Name='Zulubar'
then var_Zulubar:= Amount;
total:=total+var_Mango_ice_creame+var_Chocobar+var_Zulubar;
var_Mango_ice_creame+var_Chocobar+var_Zulubar;
Similarly create 2nd formula #second place it in Detail2
Local Numbervar var_Chocolate cone;
Local Numbervar var_Kulfi;
Local Numbervar var_ABC;
Shared Numbervar total;
if Name='Chocolate cone'
then var_Chocolate cone:= Amount;
if Name='Kulfi'
then var_Kulfi:= Amount;
if Name='ABC'
then var_ABC:= Amount;
total:=total+var_Chocolate cone+var_Kulfi+var_ABC;
var_Chocolate cone+var_Kulfi+var_ABC;
Create 3rd formula #Third place it in Detail C
Local Numbervar var_XYZ;
Shared Numbervar total;
if Name='XYZ'
then var_XYZ:= Amount;
total:=total+var_XYZ;
var_XYZ;
Create 4th formula Display and place in report footer.
Shared Numbervar total;
total;

Answer 2

Create a formula field to be used for grouping purposes:
// {#grouper}
Ceiling(RecordNumber/3)
Add a group on this field.
Create a manual, running-total field:
// {#reset}
// place in group header; suppress
WhilePrintingRecords;
Stringvar Array reset;
Stringvar Array values;
values := reset;
// {#increment}
// place in details; suppress
WhilePrintingRecords;
Stringvar Array values;
Redim Preserve values[Ubound(values)+1];
values[Ubound(values)] := {table.name_field};
// {#display}
// place in group footer
WhilePrintingRecords;
Stringvar Array values;
Join(values, ", ");
