The solution was not found

Hello

I enrolled today for a self-pace course:

BI 4 Platform Innovation and Implementation (Repeat)

I started the course and when I started to set up the environment of  the exercice of Week 1

( as per instructions provided in openSAP_BIFOUR1_Week_1_FAQ.pdf) using the link:

https://caltdc.hana.ondemand.com/subscription?sguid=a2a64e84-8cd6-4dbd-9043-a8a170f2d10d

I ended up on a dead end street: "The solution was not found".

I looked through all the existing solutions on the Solutions tab on https://caltdc.hana.ondemand.com/console

and I found no Education solution corresponding to the course....

What is wrong?
