After you locate a reject file, you can read it using a text editor that supports the reject file code page. Reject files contain rows of data rejected by the writer or the target database. Though the Integration Service writes the entire row in the reject file, the problem generally centers on one column within the row. To help you determine which column caused the row to be rejected, the Integration Service adds row and column indicators to give you more information about each column:
Row indicator.
The first column in each row of the reject file is the row indicator. The row indicator defines whether the row was marked for insert, update, delete, or reject.
If the session is a user-defined commit session, the row indicator might indicate whether the transaction was rolled back due to a non-fatal error, or if the committed transaction was in a failed target connection group.
Column indicator.
Column indicators appear after every column of data. The column indicator defines whether the column contains valid, overflow, null, or truncated data.
The following sample reject file shows the row and column indicators:
