Thanks Karol for this hint.
I seems that I overlooked some information.
So I will have to talk with our Adminsitrator to install the newest service pack and then try again or wait until the 1.5 which should work with BIP.
Maybe I misunderstood something, I thought that there is one table per application where all the translateable texts are stored. But the TLOGO object table RSAO_T_TEXT means that every object has its individual table, right?
As far as I can find all the objects in the translation environment within the BW it is no problem to translate each object.Until now I even wasn't able to find these objects here..

Steffen
