Part of an update request. An update module corresponds to a function module CALL FUNCTION ... IN UPDATE TASK. There are V1 and V2 modules in an update request: V1 modules are time-critical database changes and V2 modules are not time-critical and should only be updated when the V1 update has successfully completed.
