When using bdbpost.exe from windows command line not output file is written where to check if everything was correct and -O parameter is not working so is there any possibility to get this error log?

Based on newer information parameter -E should work for an error file.

bdpost.exe

bdbpost [-I input-file] [-O output-file] [- qE} {output-file] [- uUvVARfilxnmkKM] [-p pack_comb] [-e file] [-d driver type] [-D seq_dir] [Sep-t] [-r row / trans] [-c compnr] [-C compnr range] [pattern [<input_file]
