FPM - Validate Incorrect value entered in client specific custom fields

Dear All,

As part of client requirement, we have added few custom fields in "Standard Table - EHHSSD_INC_BINFA" using extension include provided by SAP. Now we were able to get those added fields in the enhanced component configuration and made them as Input field type.

Now when the end user fills any wrong value in any of these custom fields and then clicks on "Send" Button of "Report Incident Simplified" means we need to show an error message and stop this Incident from getting "Saved".

Any help on this would be appreciated.
