 [CLOSED]Need help on how to calculate sub-total/total for multiple inputs

Hi all,

There is a report which picks up a single Customer ID and TopXX number, and then generate the report with TopXX lines detail rows, then sub-total line for all TopXX lines, and at last the Total line for all lines in DB.

For example, if customer ID is set as '33' and topXX as '5', also in the DB there are 10 rows for the customer ID, then the report output is:

Rank Field1
1 1
2 2
3 3
4 4
5 5
Sub-Total 15 <-- its total value of topXX lines shown.
Total (1+..+10)=55 <-- its total value of all lines in DB for the customer.

For a single Customer ID, I have implement the whole report by using multiple HOLD files, calculating sub-total and total value and displaying in report.

But my boss told me to enable multiple customer IDs as input, and each customer has its own table with Sub-Total and Total. Below is the example:

Page 1 (for customer 1)
Rank Field1
1 1
2 2
3 3
4 4
5 5
Sub-Total 15
Total (1+..+10)=55

Page 2 (for customer 2)
Rank Field1
1 2
2 3
3 4
4 5
5 6
Sub-Total 20
Total (2+..+11)=65

I thought of using loop and compound function, but it might cause performance issue because each sub-report for one customer ID would query DB.

So here is the thing: is there method to calculate the sub-total and total at less performance cost for all customers?

As I understand you will have to perform DB reading one time : to extract detail customer data as per customer selection. You don't need to read DB multiple times.

Then using that hold file, perform your detail data, sub-total and customer total and have the first BY on the customer ID for those three other HOLD files.

You will then result in the same three hold files (detail, sub-total and total) with a BY CUST_ID as the first field.

Merge them the same way as you do.

Finally, produce your report and add:
ON CUST_ID PAGE-BREAK

Sample :
```TABLE FILE CAR
SUM SEATS
BY COUNTRY
BY CAR
ON COUNTRY PAGE-BREAK
ON TABLE PCHOLD FORMAT PDF
END
```

It may do the trick or be close to it.

Maybe I misunderstand the question, but wouldn't a multi-verb request do what you want?

Something like:

```DEFINE FILE XYZ
FIELD2/D12.2=FIELD1;
END

TABLE FILE XYZ
SUM FIELD2
BY CUSTID
SUM FIELD1
BY HIGHEST 5 TOPXX
END
```

You can use NOPRINT and then a SUBFOOT to display the totals for FIELD1 and FIELD2.

I confess I haven't thought this through fully and you might well have to create a hold file. Another thought is to run it twice and create one hold with the totals and another with the ranked TopXX for all the customers and then join them back together. Then, as Martin suggested, either burst by CUSTID (if you are using ReportCaster) or ON CUSTID PAGEBREAK

This will work:
```-SET &RANK = 8;

TABLE FILE USERDATA
SUM   NUMBER NOPRINT
BY    USERID NOPRINT
PRINT COMPUTE RANK/I3   = IF USERID NE LAST USERID THEN 1 ELSE RANK+1;
NUMBER
COMPUTE TOTNUM/I3 = IF USERID NE LAST USERID THEN NUMBER ELSE IF RANK LE &RANK THEN TOTNUM+NUMBER ELSE TOTNUM; NOPRINT
BY    USERID SUBFOOT
"TOTAL USERID <USERID RANKED <TOTNUM"
"TOTAL USERID <USERID DATABASE <NUMBER"
BY    HIGHEST NUMBER NOPRINT
WHERE TOTAL RANK LE &RANK;
END
```

S.G.
Try this:
```
DEFINE FILE CAR
SALES=IF SALES GT 0 THEN SALES ELSE 10000*RDUNIF('D4.3');
SFOOT/A26='Grand Total for ' | COUNTRY;
END
-*
TABLE FILE CAR
SUM COMPUTE CSALES/I6=SALES; NOPRINT
BY COUNTRY
PRINT SALES
COMPUTE L/I2=IF COUNTRY NE LAST COUNTRY THEN 1 ELSE LAST L+1; NOPRINT
BY COUNTRY
BY TOTAL LOWEST 3 L NOPRINT
ON COUNTRY SUBTOTAL
ON COUNTRY SUBFOOT
"<SFOOT<CSALES"
ON TABLE NOTOTAL
ON TABLE SET HTMLCSS ON
ON TABLE SET STYLE *
INCLUDE=ENDEFLT,
\$
TYPE=SUBFOOT, HEADALIGN=BODY,
\$
TYPE=SUBFOOT, OBJECT=FIELD, ITEM=2, JUSTIFY=RIGHT,
\$
ENDSTYLE
END
```
