How to find Count of Document no. and item in Bex report

Hi all,

I have a requirement, where user wants to see the count of Open Documents along with Item in BW report.So as a part of solution I have created a CKF with formula variable/replacement path.

My issue is if suppose one document has 3 line items then it is showing the count as 1 for that document no. however the requirement is if the item is different then Document should be counted. as an example:

Document no.      Item

10001854             10

10001854              20

10001854              30

In above case the document no. should be displayed 3 in report, however in my case it is being displayed as 1.

Please help if anyone has faced such issue in his/her project. Its bit urgent to fix now.

Thanks,

Arvind
