Hay dos maneras de crear matchcode, una es por la transacción se11 (ayuda para busqueda) y por la se38 en el mismo reporte
Crear Matchcodes (ayudas) con una tabla interna.
TABLES: VBAP,
DDSHRETVAL.
DATA: BEGIN OF IT_MATNR OCCURS 0,
MATNR LIKE VBAP-MATNR,
ARKTX LIKE VBAP-ARKTX,
END OF IT_MATNR.
DATA: BEGIN OF IT_MATCH OCCURS 0, “Esta tabla nos devuelve la ayuda
SHLPNAME LIKE DDSHRETVAL-SHLPNAME,
FIELDNAME LIKE DDSHRETVAL-FIELDNAME,
RECORDPOS LIKE DDSHRETVAL-RECORDPOS,
FIELDVAL LIKE DDSHRETVAL-FIELDVAL,
RETFIELD LIKE DDSHRETVAL-RETFIELD,
END OF IT_MATCH.
SELECTION-SCREEN BEGIN OF BLOCK BLQ1 WITH FRAME TITLE TEXT-T01.
SELECT-OPTIONS: S_MATNR FOR VBAP-MATNR NO-EXTENSION NO INTERVALS.
SELECTION-SCREEN END OF BLOCK BLQ1.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR S_MATNR-LOW.
SELECT MATNR
ARKTX
FROM VBAP
INTO TABLE IT_MATNR
WHERE VBELN EQ ‘0000000001′ AND
POSNR EQ ‘000010′.
CALL FUNCTION ‘F4IF_INT_TABLE_VALUE_REQUEST’
EXPORTING
RETFIELD = ‘MATNR’
WINDOW_TITLE = ‘Material’
VALUE_ORG = ‘S’
TABLES
VALUE_TAB = IT_MATNR
RETURN_TAB = IT_MATCH
EXCEPTIONS
PARAMETER_ERROR = 1
NO_VALUES_FOUND = 2
OTHERS = 3.
IF SY-SUBRC EQ 0.
READ TABLE IT_MATCH INDEX 1.
MOVE IT_MATCH-FIELDVAL TO S_MATNR-LOW.
ENDIF.
Espero que te sirva.
