code for SAVE functionality in FPM_OIF_COMPONENT

Hi Experts,

I have enhanced the component DPR_DET_DATA_PROJECT_O. The SAVE functionality for this component exists in FPM_OIF_COMPONENT.

I have to raise error message depending on the custom fields added in  DPR_DET_DATA_PROJECT_O when I click on 'SAVE' button.

Please share if any ideas where to write the code for SAVE functionality for the custom fields added on DPR_DET_DATA_PROJECT_O.

Regards,

Rafi
