Missing data: Answers omitted by the respondent (nonresponse), questions skipped over by the enumerator / the data entry operator or dropout (when research is undertaken overtime such as school attendance).
(I.e. the value in the questionnaire was 40,000 and the data entry operator keyed in 4,000 - a zero was left out).
Once errors have been identified, diagnosed and treated and if data collection/entry is still ongoing, the person in charge of data cleaning should give instructions to enumerators or data entry operators to prevent further mistakes, especially if they are identified as non-random.
