I had resolved this by following below procedure.
Step 1 : Implement the BADI BADI_EAM_SINGLELEVELLIST
There is one importing parameter(IV_STRUCTURE_NAME) in the method FILL_ADD_FIELDS.
So, you have to debug the transaction and to identify the structure name. Once you got the structure name, append the fields into it as per your requirement (Structure for QM14 : RQMQMFE).
Then write your data fetching part into above stated method.
