Hi Rajasekar,
Use below two BAPI to confirmation
BAPI_PRODORDCONF_GET_TT_PROP - It will be used to propose the quantity
BAPI_PRODORDCONF_CREATE_TT - It will be used to confirm order
First you have to use BAPI_PRODORDCONF_GET_TT_PROP to get activity values and then pass the values in BAPI_PRODORDCONF_CREATE_TT to confirm the order.
Note: If you want to do partial confirmation then in BAPI (BAPI_PRODORDCONF_GET_TT_PROP ) dont select the quantity (X).
