ALV F4 Functionality in Function Modules Class Definition and Implementaion in FM

former_member244850 — Tue, 20 Sep 2016 22:15:39 GMT

Hi All,

I have A Z FM that is called to display an ALV popup error message whenever an error in another Z program is double clicked, I now need to add a new field to the ALV Grid with a F4 list on one of the fields of the Function Module Pop Up message. I looked at all the Threads on SDN and they all mention the various SAP sample F$ programs like BCALV_EDIT_08.

My issue is that in these programs there needs to be Class Definitions and Implementations created Like Below (Only Partial snippet), As far as I know we cannot do this in a FM?

How can I do the same F4 functionality in a Function Module, Do I have to create Global Versions of these Classes then call them in my FM?

This is the Function Module ALV Popup Error that requires the F4 Field added to it

Thanks,

Jim

Hi,

Basically you need to add one more field to your ALV and then implement F4.

The function that displays ALV , does it use REUSE_ALV_GRID_DISPLAY to display ALV or use ALV class-method ?

Thanks

Deepak

HI Deepak,

It is using the ALV Class Method, I.E. So without being able to Define and Implement Classes as per the SAP Sample BCALV_EDIT_08. how can I get the F4 Functionality?

Thanks,

George

CREATE OBJECT co_dock_container

CALL METHOD co_grid->set_table_for_first_display

CALL METHOD co_grid->refresh_table_display

Thanks,

George.

If I have well understood your question, your biggest issue is to define a local class in your function module. You can't do it inside the function module, but you may declare it inside the function group, and use it in your function module. If your function group is named ZFUGR, you'll find a place in the include LZFUGRTOP to declare the class definition (convention is to do it inside LZFUGRD01), and a place for the implementation (convention is LZFUGRP01).

Thank You, That sounds like it will solve the issue. I will try it and let you know.
