Assistance to the issue below
The .bat file has the text immediately below and it does not like the space between external and data as evidenced by the KUP error message
KUP-04095: preprocessor command e:\external data\sbs_books\continuation_books\list_files.bat encountered error "'e:\external' is not recognized as an internal or external command.
@echo off
dir e:\external data\sbs_books\continuation_books
There are also ORA-29913: error in executing ODCIEXTTABLEFETCH callout & ORA-29400: data cartridge error. Apologies there was not enough space in the Error codes field below to include the entire text.
