GET_HISTORY

Use

The GET_HISTORY_ID method of the service object determines a global history ID. Either one reference to a data object or an individual string as history ID (history_txt) must also be transferred as the importing parameter. If a data object is specified, this must have a direct or indirect reference to an elementary dictionary type (data element), since the parameter ID specified for this data element is used as the history ID. For example, a reference to a data object with a reference to an elementary component in a Dictionary structure ( DATA: var TYPE strucname-compname) or a data object with a direct reference to a data element ( DATA: var TYPE dtelname) can be transferred.
