Hi,

Goto SE38 give BCALV* n press F4 it will display the list of all standard ALV OOps programs Refer that.

Hi sandeep,

Have a look at std program BCALV_TEST_GRID. Also look at programs under package SLIS.

Hope this helps.

Thanks

Hi Sandeep,

Check these code.here i am sending two programs.

If you are using the class cl_gui_alv_grid then you have to create a screen that containing the custom container.

If you are using the class cl_salv_table then don't need to define any custom container for getting the ALV grid.

Here I am copying the Example of both the classes .

Now its all depends upon you which class you prefer to use.

Example 1 : cl_gui_alv_grid

+ Global data definitions for ALV

ALV Grid instance reference

Hi friends;

I tried one ALV Report Program.,Based on the input ,various storage location value will be dispalyed...

example : i will(statically) generate 30 output fields using filed catalog .

based on input, in 30 fields

some of the fields the value will be dispalyed..

remains the fields the value will be un filled.

i want to generate the fields dynamically, only the fields having values....

i searching the document in net ,using field symbol it may possible... but i not having idea in field symbol....

PLZ help me....
