Use
Method GET_HISTORY_ID of the service object defines a global history ID. Either a reference to a data object or a string as history ID (history_txt) must be passed as import parameter. If a data object is passed, it must have a direct or indirect reference to an elementary Dictionary type (data element), since the parameter ID specified is used as the history ID for this data element. For example, the method can pass a reference to a data object that is associated with an elementary component of a Dictionary structure (DATA: var TYPE strucname-compname.) or a data object that directly is associated with a data reference (DATA: var TYPE dtelname.).
