CASE R_UCOMM.
WHEN 'BEAN' OR '&IC1'. "双击事件

VBTYP1 = L_SPETAB-VBTYP.
CALL FUNCTION 'RV_CALL_CHANGE_TRANSACTION'
EXPORTING

VBTYP = VBTYP1.

COL = COL_BEARBEITEN.
FARB-FARB2 = COL.

MODIFY L_SPETAB.
CLEAR: VBELN1, VBTYP1.
ENDLOOP.
IF SY-SUBRC NE 0.
READ TABLE L_SPETAB INDEX RS_SELFIELD-TABINDEX.
IF SY-SUBRC = 0.
REPLACE '1-' WITH ' ' INTO RS_SELFIELD-SEL_TAB_FIELD.
CONDENSE RS_SELFIELD-SEL_TAB_FIELD NO-GAPS.

PERFORM SELECT USING RS_SELFIELD-TABINDEX.
CLEAR FELD.
ENDIF.
ENDIF.

ENDCASE.

ENDFORM. "USER_COMMAND

2 定义一个常量包含"USER_COMMAND"
