Hello Christian.
Firstly thnx for taking your time and responding to my problem.
I already checked the Blog you mentioned .
Already opened an OSS NOTE because in one of the ABAP classes of the BRF+
there is a check missing on a field symbol assignement .
It may even be that I have missed any NOTE but I don't think it has direct impact on this problem,
maby after this get resovled the problem of the Notes i might have missed will reshow on other functionalities.
Waiting for SAP response on the note ticket I opened.
Thnx again .
BR
Elton.
