I have this step in sql server job

AAA.bat content is this
call BBB.bat
call CCC.bat
BBB.bat and CCC.bat each run ETL packages.
When I run above step it throws error
BBB.bat is not recognized as an internal or external command, operable program or batch file... CCC.bat is not recognized as an internal or external command, operable program or batch file
However, when I replace AAA.bat with either BBB.bat or CCC.bat it works as intended.
