When /e is set in such circumstances, Rebuild reports the duplicate, writes it to a duplicates file and continues to process the remaining records. The record with the duplicate key is not written to the file being rebuilt.
The duplicates file has the same file organization as the input file unless it is indexed, in which case the duplicates file is sequential. The duplicates file contains the same type of records, fixed-length or variable-length, as the input file. The name of the file is the input filename with .err appended, and it is written to the same directory as the input file.
Default
When /e is not set, Rebuild ends with an "Error on output file - status 22" error.
