Hi,

I have a report as below.
I would like to automatically add number in each group header in No. X where X will be 1,2,3,4.etc...
Is this possible?

Regards,
Marcin

Try this:

create a hidden computed field (name it "cnt" for example) with this expression:

if (first( getrow() for group 1 ) = getrow(), 1, 0)

create another computed field to show your numbers with this expression:

cumulativeSum( cnt for all )

HTH,

René

That's an interesting challenge. My first thought is to throw a page on the group change and use the page() function to give you the number. But that may not be appropriate.

I'll give it some more thought....

The only other way I can think that you can do this is with a database subquery linked to the primary query.



select groupvalue, rownum() from sourcetable group by groubvalue



This will return each groupvalue with a running count from 1 upwards, if you link this to your main query and use the value that should work.



What database are you using?



Cheers

David

Thanks David.

We use MS SQL Server.

I'll try this way if it can't be done from PB.

It should be pretty simple in MS SQL. Databases were designed to give you this stuff :-)
