Invalid Program Name; Program must contain prefix "_SLD_"

Hi

I was following this blog and trying to create a TS for my R/3 system.

Configuration Of SLD : Creation of Technical And Bussiness System

I click on the icon "Start Data Collection now " and I get this error: "Invalid Program Name; Program must contain prefix"_SLD_"

I see that already a background job is running, but that has been running from fiday, more than 720 minutes.

Any idea I am getting this error. Mine is a very new ECC system, and I haven't done any settings related to PI. I am using PI 7.4, single stack, also called PO 7.4

Regards

Harish
