SAP standard reports and ABAP proxies

Hi,

the question is about the doing to send the output of a report (i also could be a SAP standard report) via proxy to a pi system.

Our solution fpr this would be to copy the hole report and implement the changes for the proxy communication.

Is there any official SAP statement that say: "When you would do this you can only do this steps (copy report, implement changes...)"

The problem i see is that every change on the standard report has to be reviewed an implemented in the copied report.

Could anyone give me some hints, advices or best practices for this?

many thanks
