File to Idoc - Generate one segment where sourcfields have identical values

Question

Hello Team,
                      This is a Flat File to Idoc scenario where one idoc is generated at the target.
As i have mapped the Record(1..unbounded) with the E1MBXYI (1..9999), one record  in the file would create one E1MBXYI- segment in the Idoc. So if the source has four records then this would create an idoc with four E1MBXYI-segments. The requirement is, it has to generate only 1 segment for the input records(Order,Item and Date) if they have identical values.
eg., 1234,66,01032009 (Order,Item,Date)
       1234,67,01032009
       1234,68,01032009
       1234,69,01032009  - this would generate four E1MBXY1 segments in the target each for item value 66,67,68 & 69 as it has no identical item values.
eg., 1234,66,01032009
       1234,67,01032009
       1234,66,01032009
       1234,68,01032009  - this would generate three E1MBXY1 segments each for item value 66,67 & 68 in the target.The 2 identical item values for item 66 creates one segment.
How could i achieve this in the mapping, Should i go for an UDF or could it be achieved using standard functions?
Appreciate your replies....

Hi Raghavendra,
U can achieve this by simple graphical mapping.
U can do ir using following functions,
If
equlas
and
context changes.
eg.
                                                                                order                           order
                     order
                     item                   equalsS                                                         then
                                                                             and                       if
                     date
                     order                   equalsS                                                      else
                                                                                order(context change)             order
repeat the same for other fields also,
item and date....
If any doubt pl post the problem....
I hope this will be helping u...
