Maximum coloumns in ALV

[Former Member]

Hi Experts,

What is the maximum number of coloumns i can have on a classic ALV report?

Iam having a dynamic table whose number of coloumns keeps on change. So to avoid phyisical dump, i have to set a limit for the number of coloumns.

Is there any limit based on the number of charecters? even with 120 coloumns, in my ALV out put, if choose display varient, it shows line width and list width as 1640. if i click Choose button here it says 'Maximum list width (1,024 characters) exceeded'. but all the coloumns are displayed.

why is it so? Is it possible to set this line width and list witdth while calling ALV (REUSE_ALV_GRID_DISPLAY)

what are the other things to take care, with too many coloumns in ALV?

Thanking you in anticipation.

we cant set list width explicitly i think.

the list width purely depends upon the fieldcatalog.

the size of each field in fieldcatalog sums up to list width.

Hi Hymavathi,

I think there should be some option for fixing the list width. Just like the way we limit the list width in data browser. By default my list width is coming more than 1024, ( since i have more than 120 coloumns ) and i want to reduce it to a small value, so that users can scroll and see the full data, and even they can modify the display varient.

And can anyone please tell me the maximum number of couloumns one can have in a Classical ALV report? ( using reuse_alv_list_display FM)
