方法一：
"保留前导零 CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT' EXPORTING input = lv_lsh IMPORTING output = lv_lsh. "去掉前导零 CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT' EXPORTING input = lv_lsh IMPORTING
方法二：
LOOP AT s_lifnr. s_lifnr-low = |{ s_lifnr-low ALPHA = OUT }|. s_lifnr-high = |{ s_lifnr-high ALPHA = OUT }|. MODIFY s_lifnr . ENDLOOP.
方法三：
AND ltrim( b~lifnr,'0' ) IN @s_lifnr
