problem reading data from appln server

My requirement is to read data from appln server and batchinput the data to the fields.

Problem is the file in appln server has no particular structure. and it is a text file.for ex

KLART	OBJEK	CLASS	STATU	STDCL	XLINE	OBTAB	LKENZ	ATNAM	ATWRT
002	000000000000032047	W	1		1			REPA_KOSTEN_ANTEIL	                          1,9
002	000000000000032047	W	1		1			REPA_KOSTEN_ANTEIL_DATUM	13.06.2005

And also i need data only for fileds objek,REPA_KOSTEN_ANTEIL and REPA_KOSTEN_ANTEIL_DATUM
