Example of a Simple ALV Report using Function Modules (not OO)

[Former Member]

Hi,

I am new to ABAP. Where can I get a proper Example of a Simple ALV Report using Function Modules? I searched the forum but did not find a proper solution. Kindly help.

Hi,

Check this link [ALV|https://www.sdn.sap.com/irj/scn/advancedsearch?cat=sdn_all&query=alvgriddisplayusingFunction+Module&adv=false&sortby=cm_rnd_rankvalue]

> I searched the forum but did not find a proper solution.

I think you are unaware what a Function Module is.!

Initially as a beginner, to know what are all the function modules available for ALV,

goto Tcode - SE37, type REUSE_ALV* and press F4. It will give all the function modules.

With this, search here in SDN.

For sample programs:

Goto SE38, type BCALV* and press F4, it will give all the examples.

Most commonly used Function Module in ALV is REUSE_ALV_GRID_DISPLAY

some std demo programs, u can check out are:

BCALV_TEST_GRID

BCALV_TEST_LIST

BALVSD02_GRID

BALVST02_GRID

BALVST03_GRID

BCALV_FULLSCREEN_DEMO

All the Best.

Hi,

If you are aware what a Package means and if you have access to a SAP system, you will find loads of examples related to ALV programming with excellent explanation in the package SLIS. Goto t-code se80 and select "Package" from the dropdown in the object navigator and enter SLIS and press enter.

This package not only explains the ALV reporting using function modules , but also using OOPS. That is how most of us have learnt about ALV and I would suggest you follow the same path.

By any chance you dont have access to the system, go to the SCN's WIKI section and type "ALV" in the search field you will find a plethora of examples.

regards,

Advait
