REUSE_ALV_LIST_DISPLAY - I_BUFFER_ACTIVE

Hi,
Im modifying an standard program (RLINV020) to add fields to alv result, but I see that there's a property in REUSE_ALV_LIST_DISPLAY (I_BUFFER_ACTIVE) wich I don't know how it's works and what is the difference between activate and desactivate it.
Thanks in advance
Oscar

Hi Oscar,
Whatever is being displayed currently(Before you make that i_buffer_active as space) is the content of the buffer.
It is like this.
for the first time, whatever is the fieldcatalog you pass, will be considered.
Every time from then, the same that which has beed displayed wiill be in the buffer.
If you don't want to change the code , but to clear the buffer, you have to run the program: BCALV_BUFFER_DELETE once.
then whatever changes you did will be affected in the output. From this point onwards, your field catalog will be stored in the buffer(Until you run the BCALV_BUFFER_DELETE program again).
Regards,
ravi

Hi Abapers,
Please provide the sample code of class and method of REUSE_ALV_LIST_DISPLAY.
Which Class i can use for this Function module.
I need to write a code using OOPS concept.
I was done the GRID display using this class cl_gui_alv_grid.
But i want only List Display using the class & methods.
Plz provide sample code.
Thanks

Reuse_alv_list_display

I have displayed fields using "reuse_alv_list_display".
before that list display i want to display date and time but this must be displayed in the same screen where i get output from reuse_alv_list_display. how to do that

Hi,
          This can be achieved using Top of page event. while building the event for the FM pass the form name (say TOP_OF_PAGE) to the event top_of_page.
Now create a form TOP_OF_PAGE and do the required thing.
See sample code.
type-pools: slis.
types:
      begin of ty_output,
      chk type c,
      number type i,
      name(20) type c,
      end of ty_output.
data: gt_output type standard table of ty_output,
      gs_output type ty_output.

How to add two list in one frame using REUSE_ALV_LIST_DISPLAY

Hi,
I want to display two list in single output by calling FM 'REUSE_ALV_LIST_DISPLAY' twice.
I saw one topic posted by Arunava Das as 'ALV Problem' but didn't get the steps to do that.
Here is his way of doing that "What I have done is gone for the append ALV approach wher I have added the END_OF_LIST Event for the Fisrt reprt and in the Corresponding FORM Routine I have added another made another cALL to the REUSE_ALV_LIST DISPLAY FM with the other table."
I would be grateful if someone can help me out.

Hi Ashish,
The way you have tried i.e. calling the second list in the END_OF_LIST event of first list and like wise that is the correct way of doing it.
Using this way you can display multiple lists. In the event END_OF_LIST by using a global variable G_COUNTER. the value of which you increment for each list and based on that counter you call different lists in the END_OF_LIST event.
case G_COUNTER.
when 1. perform call_first_list.
when 2. perform call_second_list.
when 3. perform call_third_list.
endcase.
Hope this answers your query
regards,
Satyadev Dutta

Runtime error in reuse_alv_list_display

hi all,
i am trying to display output by using FM reuse_alv_list_display but i am getting runtime error

ENDIF.
can u please tell me where are the errors and y error is coming and how to remove it??

error in RUNTIME is
You attempted to access an unassigned field symbol
(data segment 92).
This error may occur if
- You address a typed field symbol before it has been set with
    ASSIGN
- You address a field symbol that pointed to the line of an
    internal table that was deleted
- You address a field symbol that was previously reset using
    UNASSIGN or that pointed to a local field that no
    longer exists
- You address a global function interface, although the
    respective function module is not active - that is, is
    not in the list of active calls. The list of active calls
    can be taken from this short dump.

In REUSE_ALV_GRID_DISPLAY, significance of I_BUFFER_ACTIVE !

Hi All,
We have a Report prog, which is shceduled as Batch Job.
Now what happens is this batch job gets cancelled due to lack of memory
Below is the FM used in the prog.
    CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
         EXPORTING
              I_BUFFER_ACTIVE    = 'X'

Now what i noticed is I_BUFFER_ACTIVE is 'X' in the FM REUSE_ALV_GRID_DISPLAY
What is the significance of this parameter ?
Will my problem solve if i set I_BUFFER_ACTIVE to ''.
Any suggestions are invited.
Thanks!

Hi,
Essentially, the ALV uses a two-step buffer concept for performance reasons.
Buffer A:
Complete variants including field catalog, sorting, filter
static field catalog (shared buffer)
Buffer B:
DDIC information for each field of the field catalog (Shared Buffer + Memory)
Optimized access to field catalog (Shared Buffer + Memory)
With parameter I_BUFFER_ACTIVE = 'X', buffer A is activated.If I_BUFFER_ACTIVE remains initial, the contents are nevertheless buffered in buffer B. For dynamic reasons, you have to forgo buffering completely (for example, a constant dynamic creation of structures) so that you have the following options as a developer:
1. Set SET/GET parameters ALVBUFFER to the current date.All report, variant or field catalog buffers are reset until the current date exceeds the date of the SET/GET parameter.
2. Set I_BYPASSING_BUFFER = 'X' on the call interface for the function modules and class methods.
Which type of buffering can I use for which scenario? (=developer view)
1. Activate the statically constant field catalog of buffer A with I_BUFFER_ACTIVE = 'X'
2. Semi-statically constant field catalog, for example different columns are displayed and hidden for each call.Call ALV normally, optimization is carried out implicitly by using buffer B.
3. Dynamically generated structures with field enhancements or text element changes for data elements.
How can I influence or refresh the buffers?
1. Refresh once after the structure change in a system by, for example, importing the transport request:
Set the SET/GET parameter ALVBUFFER to the current date
Execute the affected transaction/report
Delete the SET/GET parameter ALVBUFFER
Restart in a new session ( !)
2. If refreshing over a longer time of development, static scenario should be implemented in production operation
Set the SET/GET parameter ALVBUFFER to a date in the future
3. If buffer A causes problems, it can be deactivated centrally by setting the static class attribute CL_GUI_ALV_GRID=>M_BUFFER_INACTIVE='X'.
4. If you want to reset all buffers (A and B) once and centrally for all ALV applications, then execute report BALVBUFDEL.With the option "Only delete EUINFO(%F)/LTDX", all ALV buffers are reset on the current application.Then execute your report/transaction in a new session.After you have imported note 378021 or the appropriate Support Package, the entries are deleted from the selection screen and the report automatically deletes the ALV area of all active application servers.
Hope, this helps....

Total option in REUSE_ALV_LIST_DISPLAY

Hi,
If we CHECK total option in REUSE_ALV_LIST_DISPLAY we get a total of numeric value with yellow color at the bottom.
Requirement:
Let say I have 3 line item records in the display, with 20 fields and one amount field. So I get the total of the amount field. Apart from that I want the Total number of LINE ITEMS to get displayed on that line. Is that possible . How?
Thanks in Advance.

Hi Mohan Kumar,
I think this is not possible using the total option in REUSE_ALV_LIST_DISPLAY. A small shortcut is to provide another field called line item number (Populate with number 1) and use the sort parameter for the FM.Populate the sort table with the key fields of header and pass it to the FM 'REUSE_ALV_LIST_DISPLAY'.
If U dont want to see the item number also then U need to use the FM 'REUSE_ALV_FIELDCATALOG_MERGE'. Fill the first table with the Header data 2nd table with the item details and the 3rd table with the totals.

Read modified ALV Cell Data - REUSE_ALV_LIST_DISPLAY

Hi,
I am using REUSE_ALV_LIST_DISPLAY to display my ALV List. There is one editable field in this ALV output.
When user changes any value, In the ALV User Command, the updated value is not reflected.
I know, we use 'GET_GLOBALS_FROM_SLVC_FULLSCR' Function Module to get the updated data.
However its not working for me, as I am not using ALV Grid , but ALV List.
Please let me know, how to read the modified data while using ALV List.

This is old post but i put this info just in case some people have the same issue:
In user command routine i pass two parameters: the command what the user intro and the info of the row was selected. In the info of the row you must update the field refresh with 'X' value and you must update your internal table was referenced in your alv function. this work just if you was set the hotspot and input field setting in the catalog of the ALV (in this example the field "marca")
FORM user_command USING p_ucomm     LIKE sy-ucomm
                                             lw_selfield TYPE slis_selfield.
CASE p_ucomm .
     WHEN '&M_ALL'.
*       mark field "marca" with 'X' value in all rows in it_totales_wf table
       LOOP AT it_totales_wf.
         lw_selfield-refresh = 'X'.
         it_totales_wf-marca = 'X'.
         MODIFY it_totales_wf INDEX sy-tabix.
       ENDLOOP.
     WHEN '&D_ALL'.
       LOOP AT it_totales_wf.
*       unmark field "marca" in all rows in it_totales_wf table
         lw_selfield-refresh = 'X'.
         CLEAR it_totales_wf-marca.
         MODIFY it_totales_wf INDEX sy-tabix.
       ENDLOOP.
     WHEN '&IC1'.
       lw_selfield-refresh = 'X'.
*       mark field "marca" with in the row selected by the user in it_totales_wf table
       IF lw_selfield-tabindex NE 0 AND lw_selfield-fieldname = 'MARCA'.
         READ TABLE it_totales_wf INDEX lw_selfield-tabindex.
         IF it_totales_wf-marca = 'X'.
           CLEAR it_totales_wf-marca.
         ELSE.
           it_totales_wf-marca = 'X'.
         ENDIF.
         MODIFY it_totales_wf INDEX lw_selfield-tabindex.
       ELSE.
         LOOP AT it_totales_wf.
           it_totales_wf-marca = 'X'.
           MODIFY it_totales_wf.
         ENDLOOP.
       ENDIF.
ENDCASE.

How many records can be displayed with fm REUSE_ALV_LIST_DISPLAY?

Hi guys!!!
Now here's is my problem. I've been trying to display in a program wih fm REUSE_ALV_LIST_DISPLAY, aproximately 450,000 records. But the fact is that after 10 or 15 minutes the system stops the process.
This case is not the same when I display with the same function a very low number of lines.
What can I do?
Maybe one possibility is using the method for ALV List (ALV List Objects)
h2Please ur answers now!
Thanks in advance!!!
Raul Romero

Hi,
If you are not expecting to do any additional functionality that the ALV has, like, summing, sorting, filter...etc,
better display the result in a normal LIST.
or try to filter your results and in the selection screen, give an option to enter the number records you want to display in the report.

Hi Paul,
you can run the program in background by pressing F9 instead of F8. In background you have unlimited runtime and you can download the spool that has your 10000 pages.
And the object will not resolve the problem because all ALVs use the same object internally. Because it is a complex task to build the list formatted correctly it just takes its time.
When you run in background, you should set a useful layout and use the matching print format so that you get all data required. The best is to try with small lists and check the spool created.

Clemens

Standard buttons not appearing for REUSE_ALV_LIST_DISPLAY

Dear All,
I have written down an ALV report with 'REUSE_ALV_LIST_DISPLAY'. I have added a PF-STATUS with some custom buttons. When executed, the cusom buttons are visible but standard ALV buttons are not appearing. Can you please suggest why this is happening and how to avert this?
Thanks for your understanding.
Best wishes,
Atanu

Hi
Before adding your buttons, you have to copy the standard ALV status (STANDARD of program SAPLKKBL) in your status:
So in menu painter while creating your status you need to go:
Extras->Adjust Template: here set the status of ALV standard
Max

REUSE_ALV_LIST_DISPLAY give short dump beyond 100 columns

Hi,
I have more than 170 columns in my internal table and this gives short dump when it reached 100the column because the structure RS_HEADER which displays column header can only hold 99 columns.
Is there anyway I still use REUSE_ALV_LIST_DISPLAY and overcome the short dump issue.
Regards
Kasi

Although I have not encountered such a case, I would suggest the following: After 99 field, modify the field catalog by setting the excess fields as no_out = abap_true (provided TYPE-POOLS: abap is declared) Then, the user should be limited to a certain number of fields and if he/she wants more fields to be displayed, then he/she should change the layout. I hope that works.

Dump in REUSE_ALV_LIST_DISPLAY after Upgrade

Hi All
We have gone for upgrade from 4.7 to ECC 6.0
An ALV list report works fine in 4.7 , but its going for Dump in ECC 6.0.
Runtime Errors         DYN_TABLE_ILL_COMP_VAL
Except.                CX_SY_DYN_TABLE_ILL_COMP_VAL
Date and Time          17.08.2010 08:12:54
Short text
     Incorrect value in the dynamic table.
What happened?
     Error in the ABAP Application Program
     The current ABAP program "SAPLKKBL" had to be terminated because it has
     come across a statement that unfortunately cannot be executed.
When I debug it , REUSE_ALV_LIST_DISPLAY is going for dump.
Is there any OSS Notes for this ? or any other solution>
Thanks
Karthik

Since the FM is going for a dump & the error points to something being wrong in the fieldcatalog. Best bet would be to perform a consistency check on the ALV.
For this pass: I_INTERFACE_CHECK = 'X' in the call of REUSE_ALV_LIST_DISPLAY & see if there are any error messages.
Try to correct those errors if you face any problems you can post here.

Problem with REUSE_ALV_LIST_DISPLAY when report is run in background

Hi All,
I had a problem with my report I am using the REUSE_ALV_LIST_DISPLAY when I run the report in foreground the report shows the output correctly but when I run it in background the report output is broken I mean some text are cut and place under each other. Please advise solution.
Regards,
Ekit

Hello Ekit
Please, check notes below to correct it:
- 1174095 ALV print: Collective correction PRI_PARAMS_SET4
- 1039655 ALV total: Subtotals disappear from printout II
Only apply if they are relevant for your release. And always test thoroughly.
