Use the class com.idsscheer.ppm.xmlextractortools.extractor.sap2ppm.
ZLastFieldChange_sap2ppm to extract information on the last change of a document from an SAP system. Configuration and calculation of the class are the same as for the class com.idsscheer.ppm.xmlextractortools.extractor.sap2ppm.
ZFirstFieldChange_sap2ppm (see chapter Extract the first change document of a table field), only with the difference that the last change document instead of the first is used for determining the data.
