If you cannot find anything wrong with the primary file lines
using error reports, trace errors using the following
procedure.
To check for errors in a primary file:
Make a backup copy of the original migration files.
Edit the primary file to remove all lines with error
reports.
Import the edited files.
Error reports can now be eliminated.
However, if errors are still reported, the errors are in the
previous lines. The errors in the previous lines did not stop the
import but did cause problems in the next lines.
Make a copy of the backup migration files.
Edit the primary file, removing the lines previous to the lines
with error reports.
Import the edited files.
The error reports can now be
eliminated.
If errors are still reported, repeat steps 4 through 7,
removing lines previous to the lines removed in the last test.
Once you identify the problem lines, notice how they differ from
lines that were successfully imported, or how they differ from the
proper migration file format.
