We have created a Message model (DFDL), using COBOL copybook, and the model holds a Choice of below objects

1. Chc-R (Length of 42)
2. AddChc-R (Length of 100)

A portion of Cobol file is as:

Code:
16 ActRec          Pic 9(03).
               16 Chc                Pic X(10500).
               16 Chc-R    Redefines Chc.
                  20  CusChc Occurs 250 times.
                      25   BinStaCde              PIC 9(05).
                      25   BinStaSev              PIC X(01).
                      25   NibProFlg              PIC X(01).
                      25   NibBlrAccD.
                           27 NibBilAcc           Pic X(32).
                           27 NibBlrIde           Pic X(03).
               16 AddChc-R    Redefines Chc.
                  20 AddCusChc Occurs 105 times.
                      25   Add-BinStaCde          PIC 9(05).
                      25   Add-BinStaSev          PIC X(01).
                      25   Add-NibProFlg          PIC X(01).
                      25   Add-NibBlrAccD.
                           27 Add-NibBilAcc        Pic X(32).
                           27 Add-NibBlrIde       Pic X(03).
                      25   Add-NibBilAli          Pic X(20).
                      25   Add-Rsv1               Pic X(38).       


We need to select one of the above choice which parsing the message, based on a Flag available on the Fix message or now DFDL field. Any hints how this parsing can be achieved using DFDL[/code]

Use a discriminator, as described in the documentation.
