if can advise on above it'd appreciated!

you want run bat file executes job? not run command line job. right?

in case command line kitchen /job=job-path. full doc here , forum (for example) here.

the command can included in bat file, provided bat file can find kitchen excutable. have noticed pentaho removed kitchen.exe replace kitchen.bat, can copy call line.

in case want run transformation, command pan.bat.
