Id auto increment with prefix

[nithishguptak]

Hello,

I have been trying to auto increment the id with prefix- though it works without a prefix it doesnt work with a prefix and saves same.

If(
Form_JournalScreen.Mode = FormMode.New;
   With(
      {
         wList:
         Sort(
            'Journal Sicherheitsrelevante Ereignisse'.'ID_Jahr/LFdnR';
            Descending
         )
      };
      "2021/  " &     
      Text(  
         Last(wList).'ID_Jahr/LFdnR' + 1
      )
   );
   Parent.Default )

@Nogueira1306 So thing is after its saved in sharepoint it isnt updated in powerapps. I placed a trigger so that it refreshes every time there is new record.

Thank you for your time and being so helpful
