AL_RWJobLauncher: libebus.so could not be loaded

We're getting below error in SAP Backend. Via SM69, we're trying to trigger a script where it will trigger AL_RWJobLauncher.

Could not load program /app/DST1/businessobjects/dataservices/bin/AL_RWJobLauncher: Dependend module libebus.so could not be loaded.

Could not load module libebus.so. System error: No such file or directory

External program terminated with exit code 255.

But when we tried to execute the script manually in the unix level, it was successful.

The al_env.sh was enconded in the .profile of <sid>adm which is dst1adm.

What might be missing here?

Thanks!
