I have copied standard component configuration "EHHSS_INC_REC_OIF_V3_BIA_NRQ_FM" into custom and added some input fields on it. Inorder to make it read only I have enhanced the feeder class "CL_EHHSS_INC_INV_REQ_UI_FRM". In the get_data I have made read_only as 'X' in the ct_field_usage and the attribute ev_field_usage_changed as 'X'.
But the changes are not getting reflected on the screen.
Kindly help me.
