在form中的調(diào)用函數(shù)：

/:?? PERFORM GET_BSTNK_TEXT IN PROGRAM Zxxx

/:?? USING &VBDKR-VBELN&

/:?? CHANGING &BSTNK&

/:?? ENDPERFORM

在程序中實現(xiàn)：

*-----------------------------------------------------------------------
* GET_BSTNK_TEXT???????????????????????????????????????????????
*-----------------------------------------------------------------------
FORM GET_BSTNK_TEXT TABLES IN_TAB? STRUCTURE ITCSY
?????????????????????????? OUT_TAB STRUCTURE ITCSY.
DATA: tmp_vbeln LIKE vbfa-vbelv.
* read country key from in table
? READ TABLE IN_TAB WITH KEY 'VBDKR-VBELN'.
? IF SY-SUBRC = 0.
???? TMP_VALUE = IN_TAB-VALUE.
???? tmp_vbeln = TMP_VALUE.
? ENDIF.

??? CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
??? EXPORTING
????? input? = tmp_vbeln
??? IMPORTING
????? output = tmp_vbeln.

? SELECT SINGLE * FROM vbfa WHERE vbeln = tmp_vbeln
????????????????????????????? AND vbtyp_v = 'B'.
? SELECT SINGLE * FROM VBAK WHERE vbeln = VBFA-VBELV
????????????????????????????? AND auart = 'ZQT'.
? IF SY-SUBRC = 0.
???? READ TABLE OUT_TAB WITH KEY 'BSTNK'.
???? IF SY-SUBRC = 0.
??????? WRITE VBAK-BSTNK TO OUT_TAB-VALUE LEFT-JUSTIFIED.
??????? MODIFY OUT_TAB INDEX SY-TABIX.
???? ENDIF.
? ENDIF.
ENDFORM.
