Answer 1

增加一个参量 在你所要合计的FIELD 中添加一个 CFIELDNAME或者qfieldname = 你的单位的FIELD
2、Here is a simple example.
1) Add a unit field "UNIT" for PCS and TON
2) Refer to the unit measure field to the number field

REPORT ztest NO STANDARD PAGE HEADING LINE-SIZE 170.
* ALV
TYPE-POOLS: slis.

TYPES: BEGIN OF typ_data,
key(10),
num TYPE i,
unit TYPE lvc_quan,
END OF typ_data.

DATA gt_outtab TYPE TABLE OF typ_data WITH HEADER LINE.
DATA gt_fieldcat TYPE slis_t_fieldcat_alv.
DATA gt_sort TYPE slis_t_sortinfo_alv.
DATA gs_variant TYPE disvariant.
