If your RTCCTOOL report output shows a warning under the topic of “Collectors and TCOLL” , then you can check the following information to eliminate this situation.

For an example situation you can see the RTCCTOOL report output shown below ;

We should click for the detail information ;

“RSSTAT98 has System A instead of S”

Now we can check the related value via SE16 tcode

SE16 –> TCOLL –> Line : RSSTAT98 , Value of “System Type” : A

Next step is changing this value with transaction ST03N , to do this ;

ST03N –> Expert Mode –> Collector and Performance DB –> Performance Monitor Collector –> Execution Times

Select the line of RSSTAT98 and click the Change icon (Pencil)

We should change the value of “Report Type” to S instead of  A

Click OK

Click OK

Finally we have to restart the report RTCCTOOL again to see the result of the steps.

If you did everything right then you should not see any warning information anymore…
