I have done with my BDC.Data is uploading fine with
CALL TRANSACTION 'ZSINGLE' USING IT_BDCDATA MODE 'A' UPDATE 'S'
MESSAGES INTO IT_BDCMSGCOLL.
But after interacting with myself i mean when i click save then back to generate next records in my fields from excel sheet.
Rather with a click of Mouse(after giving EXCEL path excecute(F8))
all my records has to upload for this wht i have to do.
