Description: This solution describes how to resolve the error: Required Field Missing: Appeal ID
Add the appeal to the data file or in a virtual column.
If the appeal 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
Edit the User Options to match the format in the data file.
