ISP_KNVV_UPDATE

hi Experts

I am using ISP_KNVV_UPDATE function module to update price group of KNVV table by taking flat file data from user and its successfully updating it, but I want to replicate it to CRM too, but the changes in price group are not reflected in CRM.

SELECT * FROM KNVV INTO TABLE IT_KNVV FOR ALL ENTRIES IN IT_UPLOAD

WHERE KUNNR = IT_UPLOAD-KUNNR.

LOOP AT IT_KNVV INTO WA_KNVV.

READ TABLE IT_UPLOAD INTO WA_UPLOAD WITH KEY KUNNR = WA_KNVV-KUNNR.

IF SY-SUBRC = 0.

WA_KNVV-KONDA = WA_UPLOAD-KONDA.

CALL FUNCTION 'ISP_KNVV_UPDATE'

EXPORTING

KNVV_IN = WA_KNVV.

COMMIT WORK.

ENDIF.

ENDLOOP.
