Dialog Programming using ALV OOPS

Former Member — Thu, 08 Apr 2010 16:28:43 GMT

Hi,

I am developing a module pool program which contains two tabs . One tab conatins the ALV Grid and the other contains the ALV tree. In the selection screen I have a Builder, Community and LOT.

WHen I execute the transaction for the first time correct data is populating int the ALV Tree.

But when we just COME BACK and give new selection the tree is showing the previous selection data only.

I have cleared the Tree , COnatiner in the PAI event .

Used the Frontend_update method as well for the front end data update.

While debugging the corresponding internal tables are populated with the update data.

ALV tree is not refreshing right from the second run of the program with new selection inputs.

Kindly help.

Have you tried


    CALL METHOD CL_GUI_CFW=>FLUSH.
    CALL METHOD CL_GUI_CFW=>DISPATCH.

I have found that this updates internal table cache when an event is triggered outside of the tree itself.

Hi abdul,

In last triggered PAI event

write

CASE sy-ucomm.

WHEN 'BACK'.

c_container->free( ).

r_grid->free( ).

It will refresh the container and the grid then the fresh data will display.

Rgards and Best wishes.
