class method oops alv grid display error

pashasapcha — Tue, 26 Sep 2023 15:27:57 GMT

with regards to oops, I have declared 3 methods inside class definition.

1. getdata

2. display

3. handle_hotspot_click

in get data method the code is as below.

You can see I have called display inside method getdata.

in the method display I have called screen 200. (to display alv grid).The pbo of the screen 200 is to display alv grid.

I have given types and data declaration is protected section of the class.

after the start of selection, I am calling method using object (instance method).

As all the methods are inside the same class, Ideally , I should not face any issue in accessing the data.

But it is showing the internal table as unknown.

can some one suggest me why it is throwing error as I am working in the same class methods ?

Hi Mohammad Pasha

Think about coding using the class: cl_salv_table=>factory(...)

Based on the code you have posted, nowhere you have defined LT_FINAL hence the error.

Maybe you are using Ctrl+F3 (activate current include) to activate your code instead of Ctrl+F7 (activate all includes).

Every thing was working fine as long as I kept the above types and data declarations outside the class.As I am using the oops abap, so I was planning to make the method public and its types and data declarations under protected section.

You have declare something in the protected section of a class and you expect to be access from a MODULE of a Dynpro ?

First of all, WHY did you try to declare this in the class and why in the protected section ?

Why do you put ":" after statement METHOD ?

Why do you use local class ?

Why do you use old method statement : CREATE OBJECT blabla. ==> blabla = new class( importing_param = 'toto' ).

So.

in a program, the data declared before the local class definition could be accessed by anybody.

The data declare in the public section of a local class, could be accessed by the program through an instance of a class.

The data declare in the protected section of a local class, could be accessed only by a LOCAL FRIEND of the local class (pretty sure you don't want that).
