Require a Message mapping for this Logic.

Question

Hi Experts,
I require a Message mapping for this Logic.
In the Source there are 4 fields and, the Target side, the fields should appear like this.
Source Structure- File
Record
|-> Header
Order_No
Date
|-> Item
Mat_No
Quantity
Target Structure-IDoc
IDoc
|-> Header
|-> Segment
Delivery_Order_No
Recv_Date
|-> Item
|-> Segment
Delivery_Order_No
Material_Num
Recv_Quantity.
The Logic is for every Order number an IDOC is generated.And if the Material num matches then the quantity should be added. and important note  is that the material numbers are different for every order number. That means if a material number is 2 in the order number A. Then the material number can never be 2 in any of the order numbers.Here is the following with an example for the above scenario.
For example:-
we have
Source Structure- File
Order-no Date Mat_No Quantity
1 01/02/2011 A 10
1 01/02/2011 B 15
1 01/02/2011 A 10
2 01/02/2011 C 10
2 01/02/2011 C 10
3 01/02/2011 D 20
3 01/02/2011 D 10
3 01/02/2011 E 25
Target Structure-IDoc
Delivery_Order_No Recv_Date Material_Num Recv_Quantity
1 01/02/2011 A 20
1 01/02/2011 B 15
2 01/02/2011 C 20
3 01/02/2011 D 30
3 01/02/2011 E 25
           So for this example total of 5-Idocs created. That means for this example if Order_No is 1 When the Mat_No is A the quantity gets added. For this Scenario 1 IDoc with four Fields 2 in Header(Delivery_Order_No, Recv_Date) and 2 in Item(Material_Num, Recv_Quantity) is generated by adding the quantity field in the Target Side. Similarly if Order_No is 1 when the Mat_No is B  then separate IDoc is generated with four Fields 2 in Header(Delivery_Order_No, Recv_Date) and 2 in Item(Material_Num, Recv_Quantity) in the Target Side. Similarly, if Order_No is 2 when the Mat_No is C, an IDoc is generated with four Fields 2 in Header(Delivery_Order_No, Recv_Date) and 2 in Item(Material_Num, Recv_Quantity) by adding the quantity field  in the Target Side.  ike wise the process goes on upto 3.Kindly do the needy..
Thanq very much in advance..

Hi Prashanth,
Concatinate the two fields OrderNo and MaterialNo and follow the below logic which will resolve your problem.
concatinationOfOrderNo&MaterialNo>removecontext>sort>splitByValueChange>collapseContext-->IDOC
concatinationOfOrderNo&MaterialNo>removecontext>sort>splitByValueChange>collapseContext>splitByEachValue>subString(0,1)-->Delivery_Order_No
formatByExample>collapseContext>SplitByEachValue-->Recv_Date
FormatByExample:
input1:resulrOfSortByKey
input2:concatination>removecontext>sort-->SplitByValuChange
sortByKey:
input1:concatination-->removecontext
input2:date-->removecontext
concatinationOfOrderNo&MaterialNo>removecontext>sort>splitByValueChange>collapseContext>splitByEachValue>subString(1,1)-->Material_Num
formatByExample>sum>Recv_Quantity
FormatByExample:
input1:sortByKey
input2:concatination>removecontext>sort-->SplitByValueChange
SortByKey:
input1:concatination-->removecontext
input2:Quantity-->removeContext
