the create function does not working by using (business API) in RAP application

Hello

I’m trying to use BAPI_ALM_NOTIF_CREATE to implement the create function but it doesn’t work for me, i tried this code in “Behavior Implementation”:

and here’s the code on file “zcl_09_call_bapi_k” to call the BAPIs:

and i already added the field by using the UI annotations but i when i create a data then i got an empty data field:

did i missed something on the code?
