方法“GET_DATA_REF”不存在（cl_salv_bs_runtime_info），为什么？

Question

I cannot use cl_salv_bs_runtime_info=>get_data_ref as I get this syntax error:

Method "GET_DATA_REF" does not exist. There is however a method with similar name "GET_DATA"

Maybe I am using a newer or an older version of SAP or is it something else?

My code:

Answer 1

The syntax error tells you that the method doesn't exist. If you look at the concerned class and you don't see that method, then of course it means that it doesn't exist in your system.

Software keep evolving. In new versions there are sometimes new programs, sometimes others are deleted. That's life...

PS: note that the class cl_salv_bs_runtime_info is not officially supported. Use it at your own risk.

Answer 2

I've recently stumble upon the same problem.

This error is caused by cl_salv_bs_runtime_info version don't have method GET_DATA_REF.

You might want to try to read this article https://blogs.sap.com/2011/07/07/gain-programmatic-access-to-data-of-sapgui-alv-reports/ .

In the near end article they describe the difference between get_data_ref and get_data. Since we do not have get_data_ref, if we want to retrieve alv data from submit program we can only use get_data report. You might have notice that in this version there is parameter structure in

cl_salv_bs_runtime_info=>set( EXPORTING display = abap_false metadata = abap_false structure = '' data = abap_true ).

This is because method get_data can not be used for dynamic table. Before retrieving the data we need to know its structure first. Since you want to submit standard program RFKSLD00, you can first search for the structure used in them. After finding the structure you can put the structure name in structure parameter.

After that, you can declare an internal table using the structure submitted above and put the internal table in to t_data parameter in get_data method.

Hope this answer will help.
