Regarding Message Mapping Logic ...!

Question

Hi Experts ,
I am working on the the below requirement  JDBC to IDoc scenarion in the mapping i need the below logic
based on the existence of the Transaciton ID . the idoc followed by the segments should be created . for ex
If Interface_Trasaction_ID= 456  THEN   Idoc 1 followed by Segments and line items
                                                                E1BPACHE09,
                                                                E1BPACCR09
                                                                E1BPACCR09,
                                                                E1PACEXTC  .
                                                                    Field value=456
If Interface_Transaction_ID =457 THEN  Idoc  2 followed by Segments and  line items
                                                               E1BPACHE09,
                                                               E1BPACCR09
                                                               E1BPACCR09,
                                                               E1PACEXTC  .
                                                                    Field value=457
To satisfy the above logic i have mapped Transaction id > SplitByValue->CollapseContext--->Idoc
But the same Mapping Logic is not working when Sender payload is triggred having  Repeated Transcation_Id value ias given below if Transaction ID= 456 ,
              Transaction ID= 457,
              Transaction ID= 457,
              Transaction ID= 456 .
then  output should have only 2 Idoc  Followed by segments where Field Value will be 456, 457
I have mapped Transaction id -->Field Value .
let me know how can achive the above logic ...!!

Hi Aziz,
you can use UDF
Transaction IDRemoveContext-->sortUDF- SplitByValue->CollapseContext--->Idoc
public void removeDuplicate(String[] Value, ResultList result, Container container) throws StreamTransformationException{
String temp = Value[0];
result.addValue(Value[0]);
for(int i=0;i<Value.length;i++)
   if(!(Value<i>.equals(temp)))
        result.addValue(Value<i>);
   temp=Value<i>;
