Editable ALVs vs Table Controls

Hi...
Can somebody give me the advantages and disadvantages of using editable ALV's (ALV grid) over table controls? I've got a requirement from my client side wherein I have to replace all table controls with editable ALV's and prior to that, I've to submit an understanding document highlighting the advantages and disadvantages of doing the same. Also, I've heard that SAP is thinking of replacing all existing table controls in its standard screens with editable ALVs. Can somebody send me a link or some article to substantiate this?
<removed>. Please do help me out asap if you feel like it.
Thanks and Regards,
Rakesh

> And also, if its true that SAP is thinking on replacing table controls with editable ALV's
SAP usually don't spend time to rewrite existing programs. Many efforts and risks of regression for a so little gain. Really, that would surprise me
That would be rather easy to show ALV advantages, as you can do almost "nothing" with table controls. So I would begin with the only table control functions:
- change order of columns
- hide columns
- change column size
- save the layout above, for the user and for everyone
- number of fixed columns
- good performance in the WAN as only screen lines are loaded
ALV can do all of them. The other ALV functions are : see [SAP library - SAP List Viewer for SAP GUI|http://help.sap.com/saphelp_nw2004s/helpdata/en/8d/e994374c9cd355e10000009b38f8cf/frameset.htm]).
Another difference is that checks are done immediately for current page of table control (when you press enter or scroll, the PAI is triggered), while they are done for the whole lines with ALV (in fact you could do it, but I guess you don't want to spend much time to develop)

Search help (PREM) for personal no. is not coming in ALV grid table control

hi experts,
Search help (PREM) for personal no. is not coming in ALV grid table control.
i have assigned the srch help (prem) to my 'ZFIEXP_PROJALLOC' table for the emp_id.
but in output it is now showing the help.
ls_fcat-fieldname = 'EMPLOYEE CODE'.
ls_fcat-ref_table = 'ZFIEXP_PROJALLOC'.
ls_fcat-ref_field = 'EMP_ID'.
ls_fcat-outputlen = '10'.
ls_fcat-key = 'X'.
ls_fcat-edit = 'X'.
ls_fcat-coltext = 'EMPLOYEE CODE'.
ls_fcat-seltext = 'EMPLOYEE CODE'.
append ls_fcat to pt_fieldcat.
clear ls_fcat.
Then i tried to solve it using the PA0002 . ie.,
ls_fcat-fieldname = 'EMPLOYEE CODE'.
ls_fcat-ref_table = 'PA0002'.
ls_fcat-ref_field = 'PERNR'.
ls_fcat-outputlen = '10'.
ls_fcat-key = 'X'.
ls_fcat-edit = 'X'.
ls_fcat-coltext = 'EMPLOYEE CODE'.
ls_fcat-seltext = 'EMPLOYEE CODE'.
append ls_fcat to pt_fieldcat.
clear ls_fcat.
with this it is showing the help in employee code, but, when i click on an empl number, it is not added to my table control and allowing me to add the number by typing them.
plz help me.
thanks.

Hi
In the layout give layout-sel_mode = 'A'. and
pass 'A' to i_save exporting parameter to method set_table_for_first_display.
The same thing if you are working with function module
reuse_alv_grid_display.

Please show me where to put my codes to edit(edit directly on table control fields) and update my table control(using the 'save' button)?

Hi,
You have to put the following code in the PBO of screen 1000.This code would make the fields editable to make changes in the table control fields directly.
Here there are 3 transactions.For create and change transactions, the fields will be in editable mode and for display transaction,they will be non editable mode.
DESCRIBE TABLE tb_line LINES lin.    " tb_line is the name of the internal table for the table control
tcl_item-lines = lin.                             '' lin hold the number of lines of the internal table
CASE sy-tcode.
    WHEN 'ZCREATE09' OR 'ZCHANGE09'.
***Checking if the table control is empty or not***
      IF lin NE 0.
        LOOP AT SCREEN.
***To make the screen editable****
          screen-input = 1.
        ENDLOOP.
      ELSE.
        LOOP AT SCREEN.
          IF screen-name CS 'TB_LINE'.
****To make the screen non-editable if no values are present in the
***table control****
            screen-input = 0.
            MODIFY SCREEN.
          ENDIF.
        ENDLOOP.
      ENDIF.
Once the fields are edited and the save button is pressed,the entered values have to be populated into the Z tables.The code has to written in the PAI of the screen 1000.Here the values from the work area of the internal table are moved into the Z Table. The code will be.
LOOP AT tb_line.
    ztm09_ekpo-ebeln = ztm09_ekko-ebeln. "ztm09_ekko and ztm09_ekpo are the names of the Z Tables.
    ztm09_ekpo-ebelp = tb_line-ebelp.
    ztm09_ekpo-matnr = tb_line-matnr.
    ztm09_ekpo-menge = tb_line-menge.
    ztm09_ekpo-meins = tb_line-meins.
    ztm09_ekpo-netpr = tb_line-netpr.
    ztm09_ekpo-waers = tb_line-waers.
*****Update the entries into item table*****
    MODIFY ztm09_ekpo.

Difference between ALV and Table control

Hi folks,
i want to know the major differences between AlV and table controls.
i know that table control is designed in screen painter, but i want to know the major diff between Table control and ALV.
helpful answers will be rewarded.
Regards,
Naveen

Hi Naveen,
Basically ALV is a way to display the output and Table Control is designed in screen painter through which you can get entries in Table Control, can delete some records etc for further processing and its not use only for Display.
<b>ALV is Application List viewer:-</b>
Sap provides a set of ALV (ABAP LIST VIEWER) function modules which can be put into use to embellish the output of a report. This set of ALV functions is used to enhance the readability and functionality of any report output. Cases arise in sap when the output of a report contains columns extending more than 255 characters in length.
In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report display. This is a very efficient tool for dynamically sorting and arranging the columns from a report output.
<b>TABLE CONTROL:-</b>
ABAP offers two mechanisms for displaying and using table data in a screen. These mechanisms are table controls and step loops. Table controls and step loops are types of screen tables you can add to a screen in the Screen Painter.
Rewards if useful.

Drag and drop ALV to table control

Hi all,
Does anyone know if it is possible to program the drag-and-drop functionality from an ALV list to a table control? I would like to have this feature to let the user enter data on 1 screen. On the left part the user sees an ALV list and on the right the user sees the online transaction. I would like the user to enter data simply by drag and drop instead of having to enter the data.
Does someone has a sample program for this?
Regards,
Kris

Hi Kris
I can download the programs and send them to you, but you should give me your e-mail.
Anyway you can use Drag and Drop if you build your table control by ALV, i.e. ALV GRID.
But I'm using 4.7 and I don't know how class CL_GUI_ALV_GRID is in your release, I believe the release 4.6B is one of first release whit this class.

Editable columns in table control?

Hi Gurus,
I am using table control. When I click one button(Add Structure ) i am creating table rows with data, example it creates 3 rows everytime on click on this button. But coming to colmns, for first row i want first 2 columns are in edit mode, in 2nd row 3, 4th colms are in edit and in 3rd row last 2 cols are in edit mode.
For this i searched in this form i got some solution, i applied that but i am getting first row all columns in edit mode.
I tried like this ... I created 3 attributes INV1, INV2,INV3 of type wdy_boolean in node. binded with enable property first 2 cols to INV1 like that. and on ADD_STRUCT button action code like this.
DATA lo_nd_structure TYPE REF TO if_wd_context_node.
DATA lo_el_structure TYPE REF TO if_wd_context_element.
DATA ls_structure TYPE wd_this->Element_structure.
data lt_structure type wd_this->Elements_structure.
navigate from <CONTEXT> to <STRUCTURE> via lead selection
lo_nd_structure = wd_context->get_child_node( name = wd_this->wdctx_structure ).
ls_structure-month1 = First Month.
APPEND ls_structure TO lt_structure.
ls_structure-month2 = Sec Month.
APPEND ls_structure TO lt_structure.
ls_structure-month3 = Third Month.
APPEND ls_structure TO lt_structure.
lo_nd_structure->bind_table( new_items =   lt_structure    set_initial_elements = abap_false ).
DATA DIS1 TYPE WDY_BOOLEAN.
DATA DIS2 TYPE WDY_BOOLEAN.
DATA DIS3 TYPE WDY_BOOLEAN.
DIS1 = ABAP_TRUE.
DIS2 = ABAP_FALSE.
DIS3 = ABAP_FALSE.
lo_nd_structure->set_attribute(
   name = `INV1`
value = DIS1 ).
DIS1 = ABAP_FALSE.
DIS2 = ABAP_TRUE.
DIS3 = ABAP_FALSE.
lo_nd_structure->set_attribute(

Hey Madhan,
Try is like below.

Can not deselect edit position in table control

A table control has a property called editpos. This property returns the cell cordinates for the cell that the use is editing and is writeable. The property correctly returns -1 and -2 values depending if a header is selected or nothing is selected, however, if a -1 or -2 is written to the property it just selects cell 0,0. Is this behavior a bug?
I wanted to input -2,-2 to deselect the current cell that is being edited. Anyone have another idea on how to achieve this?

Thank you for the reply. Actually, I am not interested in the table data. I am only interested in the current edit position within the table control. The table property editpos states
Edit Position Property
Property of Table.
The row-column pair index of the current text entry. Values of (0,0) indicate the top-left text entry. A value of –1 indicates the row or column header. Values of (–2, –2) indicate that no edits are being made to the text of the control. This property does not set text focus on a control that does not already have text focus.
Since the property returns cordinates for selected column headers (-1,x), row headers (x,-1) or no selection (-2,-2). I was surprised if I tried to write a value of -1 or -2 to either the row or colum it would act as if I had typed a 0. For example, (-2,-2) would select cell (0,0) and (-1,4) would select cell (0,4). This behavior seemed like a bug to me or should at least be noted in the property help file.
I did manage to find a solution for my particular problem however. Since I am not trying to move to the header row or column and just wanted to deselect the current edit position I just set KeyFocus to false.

ALV vs Table Control

Hi All,
Could someone please tell me whether ALV is faster or Table Control. I mean for processing. The features required are Colouring cell, Adding checkbox in cell, adding a link in cell etc.
I know that this is possible in ALV, but no idea whether it could be done in table control. Please throw some light on this.
Please let me know the reasons behind one being faster than another.
Thanks in advance.
Best regards,
Prashant

Hi Prashant,
ALV Grid is basically used for display puropse. It is more user friendly. There are arious features ( such as coloring, sorting, saving to a local file, sedning by mail etc. ) These featurs make ALV Grid a very good option to display the data .
However , the table control is not only used to display data take from the database table, but also you can do operation such as deletion of data from database table, insertion of data into the database table and updation also. Yeah it has not got the various features whihc ALV has.
So table control and ALV Grid , if you are just using for display purpose, then ALV Grid is a better option due to its layout and attractive features. But if you want to do the database operations other than display, table control can be used.
As far as execution is concerned, I think ALV Grid is faster.

The first row should be editable in a table control

Hi Everyone,
I have a requirement for a screen, where we have a table control and we allow only a column to be in editable mode.
Now we dont require the entire coulmn to be on editable or input mode, we require only the first entry(latest entry) to be in ediatble mode. Rest should be in display mode.
Can we accomplish this.

Make Non-editable Column in Table Control of ME21N and ME22N

Hi Experts,
I was trying to look for a solution to make the columns for field MEPO1320-SLFDT(Stat Deliv. Date), MEPO1320-EEIND (Deliv. Date) and MEPO1211-NETPR (Net Price) from transaction ME21N and ME22N to be non-editable ONLY when Qty Received (MEPO1320-WEMNG) > 0.
I'd found that the modify screen codes were located at Class CL_TABLE_VIEW_MM, Method MODIFY_SCREEN_TC_LINE but there were no enhancement spots available to add my code. Is there any other method i can use to make those fields non-editable?
Thanks in advance!
Cheers,
Cheng
Edited by: Cheng Mei Tan on Jun 4, 2009 9:31 AM

Hi Cheng,
I think you can use this BAdi: ME_PROCESS_PO_CUST - Enhance Processing of Enjoy Purchase Order.
Use the method PROCESS_ITEM to control the fields at the item level.
I think is not possible to make the fields non-editable, however, you can put an error message whenever your condition is verified, and the user won't be able to change the fields.
Cheers,
Pedro

What are the prerequisites before creating a Table Control?.

What are the prerequisites before creating a Table Control?.

It depends on the kind of application you want to develop....You can use Editable ALV or Table Control......
If you need a table control...The best is create an Structure in SE11 to assing the fields to the table....It's easy -;)

Error in editing table control in module pool

Hello Abap experts,
I am working on module pool.
When I am editing row in table control if table control has only one row to edit(By clicking edit push button) then I am getting error as "Dynpro_Field_Conversion error" in module pool.
Error is showing in PBO 'module fill table control'.
But if there are more than 1 rows in table control it doesn't give any error and run successfully.
So please help me on that.
Thanks!

How to modify changes of table control data in PAI

I have a table control where the columns are brought by dict fields.I am able to bring data into table control through an itab.
Now what i want is whenever user edits data in table control and clicks on save button the corresponding changes should be made in database.
