I am new in SDK, I am working on SAP Business One Studio in SAP B1 9.1,.
My problem is when I open my b1s form in C# and try to add a System Form nothing comes in the list.
Steps I took is:-
1.) Create a C# New Project with SAP Business One Add-On Project Form B1s File and add my b1s file in it.
2.) I added a button in the form and replace a line of throw new System.NotImplementedException with
3.) Open some commented codes and run the project.
4.) I was able to see the reflections on SAP with new module and my form.
5.) Now I tried to add an existing System Form of SAP, but nothing was there in the list as shown below.
Please tell me why the list is empty.
