Need help in FPM Development

Hi Team,

I am working on one FPM development based on Web Dyn. Component "FPM_OIF_COMPONENT". My query is regarding Modifying one of the FORM UIBB to include customer specific

fields.

To summarise

I have created :
Application                                         ZEHHSS_INC_REC_QAF  (Copy of EHHSS_INC_REC_QAF)
Description                                        Custom Report Incident - Simplified
Component                                        FPM_OIF_COMPONENT

(Application) Configuration Name         ZEHHSS_INC_REC_QAF (Copy of EHHSS_INC_REC_QAF)
Description                                        Custom Application Configuration for EHHSS_INC_REC_QAF
Web Dynpro Applicat.                         ZEHHSS_INC_REC_QAF

(Component) Configuration Name          ZEHHSS_INC_REC_QAF
Description                                         Custom Component Configuration for EHHSS_INC_REC_QAF
Web Dynpro Component                      FPM_OIF_COMPONENT

It is having Many FORM UIBB and LIST UIBB with their corresponding UIBB Configurations

One of them is

Form UIBB (1.3)
Component Name: FPM_FORM_UIBB 
View: FORM_WINDOW 

Configuration Name: EHHSS_INC_REC_QAF_BINF_FRM

Feeder Class : CL_EHHSS_INC_Q_LOC_UI_FRM

Requirement : I have to add some more client specific field to his configuration. For this reason I have copied this configuraion to "ZEHHSS_INC_REC_QAF_BINF_FRM" and added custom fields to this config.

Now Need your help in suggesting where to write code/validation for custom fields. I hope I need to write code in Feeder class only..but at which place.

Please suggest

Warm regards
