Split the value using comma as delimiter and then pass each value to query to get the description

Question

Hi,
As i am new to crystal reports,  I need help in getting one field.
In my report i am using 2 tables:
one is like :
code_id
code_desc
1
aaa
2
bbb
3
ccc
4
ddd
and the another is :
reason_ind
1
2,3,4
2,3
1,2,3,4
3,4
In this report i have a column : Reason_desc.
Here i have to show code_desc for those values of reason_ind matches with code_id in the above table.
Ex:
reason_ind
reason_desc
1
aaa
2,3,4
bbb,ccc,ddd
2,3
bbb,ccc
Let me know if you need further clarifications.
Thanks in advance.
Regards,
Swathi.

Hi Swathi,
Here's how you can do this at the report level:
1) Create a Main report pointing to the second table from that screenshot.
2) Drag and drop the Reason_ind column on the Details Section
3) Insert a Subreport pointing to the First table and place it on the Details Section
4) Right-click the Subreport > Select Change Subreport Links > Move the Reason_Ind field to the pane on the right > Uncheck the option 'Select data in Subreport based on field'
5) Get inside the Subreport and go to Report > Selection Formulas > Record and use this code:
ToText({Code_Id},0,"") IN Split({@Pm-Reason_Ind},",")
6) In the Subreport, create a Group on the Code_Desc field
7) Suppress the Report Header, Group Header, Details and Group Footer sections
8) Create a Formula with this code and place it on the Group Header 1 section:
whileprintingrecords;
stringvar s := s + {Code_Desc} + ", ";
9) Create one more formula and place this on the Report Footer section:
whileprintingrecords;
stringvar s;
Left(s,len(s)-2);
Hope this helps.
