Explain the three methods used to correct errors in data entry
Correct immediately. In the direct data validation approach, error detection and correction take place during data entry. When an error or illogical relationship is entered, the system should halt the data entry procedure until the error is corrected.
Create an error file. In the delayed data validation approach, errors are flagged and placed in an error file. Records with errors will not be processed until the error is investigated and corrected.
Reject the batch. Some errors are associated with the entire batch and are not attributable to individual records. An example of this is a control total that does not balance. The entire batch is placed in the error file and will be reprocessed when the error is corrected.
