identifier 'EXCEL2COLLECTION.TP_SHEETS' must be declared
I am getting the following error when I try to run the EXCEL2COLLECTION process PLS-00201: identifier 'EXCEL2COLLECTION.TP_SHEETS' must be declared
The error "PLS-00201: identifier 'EXCEL2COLLECTION.TP_SHEETS' " is something you can ignore. The second error "ORA-06502: PL/SQL: numeric or value error" is more serious. That means it can not parse the XLS-file. Without that file it is impossible to say why that is happening.
You could try that XLS-file at my demo application for this plugin at Demo application for EXCEL2COLLECTION That application uses the "package-parser" which, besides being much faster, provides more logging for me to debug.
I removed the code to try using "a" package.
