Hello Deepak,
BRF+ structures and data elements that are automatically created when you create a BRF+ table bound to a DDIC table type, can be used independently to the BRF+ table object itself.
Which get the fields information from the structures
FDTS_WD_DDIC_QUERY_PARAMS and FDTS_WD_DDIC_WHERE_USED_LIST
Check the below program to know the DDIC binding for data objects
FDT_DDIC_BINDING_UP_TO_DATE
hope it helps
Regards
Baithi
