I recorded BDC using PA40 transaction it is working finr in call transaction mode. when all infotypes has been processed it is comin to initial screen of PA40 transaction. initially i am not giving poersonal number i am giving only "from date". personal number will generate when this bdc called the infotype 0001. after the execution of this bdc at last it is coming to initial screen there it is showing personal number which is generated in inoftype 0000. any body can tell me how to clear pernr and fron date. so that for next record it will consider flat file data.
