ALV list/grid in a loop

[Former Member]

Experts,

I have requirment where-in i have to display 3 ALV lists in loop.

The field_catlog remains the same for 3 lists but the table data is going to be changed (Ex: based on material no and plant).

As of now it is displaying last set of data on the screen but when i hit back button it shows previous set of data and so on..

is there any way to dispplay evrything at once?

Thanks.

Hi, you must use ALV grid Control for doing that. When Creating ALV's with class cl_gui_alv_grid you can Split the screen in three parts and every part can have a different ALV display. If i understood the question wrong please let me know.

I think there is misscommunication.

it is not just 3 lists, it is just set, no' of list-set may vary with input at run time.

i need to display as below:

list1

list2

list3

list11

list22

list33

list111

list222

list333

and on...

but 3 field catlog remains same only data varies...

Then in that case you call the function

REUSE_ALV_BLOCK_LIST_APPEND in loop, and pass different data to that.

Thanks Vijay !

do you have any examples for that?

[former_member188685]

I tried it long time back, i used Deep structures and passed , and it worked fine in my case. you show me your code. we can see what is wrong.

[Former Member]

Vijay, I could work around that.

what is the No' of lists it displays?

In my case: for less no' of lists it displays very well. and if I'm trying to dispaly more no' of lists it is getting short dump.

[former_member188685]

what is the Dump says..

I tried it for 5 or 6 Lists.

How many in your case..?

[former_member188685]

You can go upto 29 lists. if it crosses then it gives dump.

Vijay,

But in my case it may exceed 29 lists, in that case how do i handle?

[former_member188685]

will some one see that kind of report...?

anyway..if you copy the function REUSE_ALV_BLOCK_LIST_APPEND then change the logic you may get the functionality.

copy of one function may not be sufficient, you should copy other two also. since some data and variables shared by the functions, since all of them are in one function group.

use normal ALV list with group functionality you can get same output. just check that option..

The thing is for each material i have 3 lists to display (this is the requirement ) . so if i give 10 materials it will work fine (which will have 30 lists to display) but for 11 n more it will not work.

my program restrict the user to 25 materials as of now (then in this case it is not possible to display multi lists i.e it need to display 75 lists), which is not possible.

even if i restrict the user to only 10 materials, the 11 n more materials are run at the background, that is how my code handles.

Kindly let me know, how do i acheive this.

[naimesh_patel]

I think for your requirement, you can use the IT_SORT table of the simple ALV.

FM: REUSE_ALV_LIST_DISPLAY

Parameter: IT_SORT

IA_SORT-SPOS = '01'.
IA_SORT-FIELDNAME = 'MATNR'.
IA_SORT-UP = 'X'.
IA_SORT-GROUP = '*'.  < This will generate a Group on the output
APPEND IA_SORT TO IT_SORT.

* Use FM REUSE_ALV_LIST_DISPLAY to generate the list

You can look at the report FBL5N. It is generating the report based on the Company Code and Customer groups.

Thanks Naimesh , i got it resolved by your answer..

[Former Member]

you have to create 3 custom containers and assign the list/grid to these containers.

or check this standard report.

with out looping you can do that using the BLOCK list. it is a simple one.

Need to call the Functions

REUSE_ALV_BLOCK_LIST_INIT "Only once

REUSE_ALV_BLOCK_LIST_APPEND "Three times you need to call for 3 lists

REUSE_ALV_BLOCK_LIST_DISPLAY "Only once
