BADI FIN_TRV_REQUEST_ONSAVE for Fiori app "Travel request for Travel assistant" not stopping

[M_ASHHAR]

Hi ,

I have added an additional field in Travel Request for assistant through CFL and implemented a BADI "FIN_TRV_REQUEST_ONSAVE" for validation at the time of save. Issue is, it is not stopping the user even added type 'E' message in ct_messages.

ls_message-type = 'E'. "Warning Message
ls_message-id = '56'.
ls_message-number = '840'.
ls_message-message_v1 = 'This is a test for BAdI Extensibility '.
ls_message-message = 'This is a test for BAdI Extensibility '.
APPEND ls_message TO ct_messages.

I have also tried to use "cx_ble_runtime_error" exception still it is not stopping. Please help or let me know if I need to add any more code in this .
