Question

What control issue is related to reentering corrected error records into a batch processing system? What are the two methods for doing this?

Answer 1

Errors detected during processing require careful handling, since these records may already be partially processed.
Simply resubmitting the corrected records at the data input stage may result in processing portions of these transactions twice.
Two methods are as follows:

i. reverse the effects of the partially processed transactions and resubmit the corrected records to the data input stage

ii. reinsert corrected records into the processing stage at which the error was detected.
