Values not getting updated in Classification tab by BAPI_BATCH_SAVE_REPLICA

Hello Experts ,

I am currently facinmg problem with value updation in Classification Tab for Batch Master. To create the classification I have marked BATCHCONTROLFIELDS-DOCLASSIFY = 'X' and to pass values to classification I have done the below coding.

wa_classvaluationschar-value_char = wa_itab-value1.

APPEND wa_classvaluationschar TO it_classvaluationschar.

wa_classvaluationsnum-value_from = wa_itab-value1.

wa_classvaluationsnum-unit_from = wa_itab-meins.

APPEND wa_classvaluationsnum TO it_classvaluationsnum.

Finally called the FM 'BAPI_BATCH_SAVE_REPLICA'. But , inspite of this I am not able to see values in the created Batch. Please advice on the same.

Thanks
