Hi all,
I forgot to update our findings. We made a test: we created a new environment called "ZTEST" from Web Admin (let's say we were working on client 300), the process finished with no errors but the environment once created disappeared from the screen.
We later noticed that BPC component was installed in one client (300) and BW in another client (let's say 001).
I have never worked with an architecture like this, but my environment "ZTEST" was automatically saved in client 001, even when I was log on in 300 and in client 300 nothing was really saved.
So, It seems it was some change made by Basis team. But we were in a hurry, because we had to present a demo, so we ask to basis installed both components in the same client in order to work.
Thanks a lot for your help.
