Summation of amount and quantity

Hi all,

I have the ITAB_MSEG as follows.

wa_mseg-mblnr = '5000000130'. "Number of Article Document

wa_mseg-mjahr = '2008'. "Article Document Year

wa_mseg-bwart = '901'. "Movement Type (Inventory Management)

wa_mseg-dmbtr = '00000005000'. "Amount in Local Currency

wa_mseg-bpmng = '00000000100'. "Quantity in Purchase Order Price Unit

wa_mseg-ebeln = '1059200855'. "Purchasing Document Number

wa_mseg-ebelp = '00010'. "Item Number of Purchasing Document

APPEND wa_mseg to itab_mseg.

wa_mseg-mblnr = '5000000131'. "Number of Article Document

wa_mseg-mjahr = '2008'. "Article Document Year

wa_mseg-bwart = '902'. "Movement Type (Inventory Management)

wa_mseg-dmbtr = '00000002500'. "Amount in Local Currency

wa_mseg-bpmng = '00000000050'. "Quantity in Purchase Order Price Unit

wa_mseg-ebeln = '1059200855'. "Purchasing Document Number

wa_mseg-ebelp = '00010'. "Item Number of Purchasing Document

APPEND wa_mseg to itab_mseg.

wa_mseg-mblnr = '5000000132'.

wa_mseg-mjahr = '2008'.

wa_mseg-bwart = '901'.

wa_mseg-dmbtr = '00000002500'.

wa_mseg-bpmng = '00000000050'.

wa_mseg-ebeln = '1059200855'.

wa_mseg-ebelp = '00010'.

APPEND wa_mseg to itab_mseg.
