Here is on more go ! Need a shortcut for my problem !

problem is i have a look_update with fixed sequence of column
that is :

MANDT:SERAIL:SERSCHA:SEREX:EQTYP:BSTVP
I will be getting data in a flat file having same number of column but the sequence could be different in each time

for example
SERAIL MANDT SERSCHA SEREX EQTYP BSTVP
510 1 f g s r
510 2 g S t
510 3 g S 2
510 4 g S 2
510 Z001 g S
510 Z004 f gr S 2
510 ZPM1 f er M 1
510 ZPM2 76 M 1

here the sequence of the column is not what it in look up string
it should be in the sequence of look up string .
I want to arrange the data of this table in look up sequence and put it into another filnal_data file

each time the clientdata may come in differnt sequence but i have arrange the column in the sequence of lookup_string and append it to final table

Hope u all got my problem ! please assist
