SAP PI/PO: Java Program to fetch the values from value mapping table

The below java code in ESR will take the data from the value mapping table maintained in ID

String context = "http://sap.com/xi/XI";

   String senderAgency = "ECC";

        String senderScheme = "Directory";

        String receiverAgency = "Bank";

        String receiverScheme = "Filename";

        

        IFIdentifier source = XIVMFactory.newIdentifier(context, senderAgency, senderScheme);

     IFIdentifier target = XIVMFactory.newIdentifier(context, receiverAgency , receiverScheme);

        IFRequest request = XIVMFactory.newRequest(source,target,filename_bank_concat);

        String destvalue = "";

      IFResponse response = XIVMService.executeMapping(request);

           String[] targetValues = response.getTargetValues();

           // take first value of result

      if(targetValues.length>0)

      destvalue= targetValues[0];

You can use the destvalue and perform your logic.
