xsl 1.0 muenchian sum to sum quantity field per compound key
问题 For a SAP PO xsl 1.0 mapping I need to map an 'exotic' file coming from our warehouse where I need to group/sum per order (RECH) a QTY field on a combination of a line identifier (MASTER_PO_LINE_NO) and an Itemnumber (SKU). Each line (RECL) is in a header (RECH). INPUT: <?xml version="1.0" encoding="UTF-8"?> <ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge"> <ns0:Message1> <MARCXML> <RCIC> <RECH> <SALESID>24000</SALESID> <RECL> <LINE_NO>1</LINE_NO> <QTY_EXPE>1592</QTY_EXPE> <SKU
