Description: Occurs when package id can not be recognized or is missing from import
Add the package id to the data file or create a virtual column to use for importing the package id value.
If the package id is already present in the mapping, this error can occur if there is a mismatch between the format in the data file and what The Raiser's Edge is expecting.
To check the User Options, go to RE-->Tools-->User Options-->Records-->Appeal (whatever format is selected for the appeal is what the package id will follow)
Edit the User Options to match the format incoming from the data file.
