This indicates if the corresponding condition does or does not require user acknowledgement. Conditions that require user acknowledgement will have a value of 'required'. Those conditions that do not require user acknowledgement will have a value of 'notRequired' or in some devices the column may not be present at all. If a condition requires acknowledgement it will remain in the table until both the 'lgpConditionCurrentState' and 'lgpConditionAcknowledged' are 'inactive' and 'acknowledged' respectively (see lgpConditionAcknowledged). If a condition does not require acknowledgement it will be removed from the table as soon as its 'lgpConditionCurrentState' is 'inactive'.
