Check_changed_data method on editable ALV Grid ( class cl_gui_alv_grid)

Hi guys,
I use the following method (register_edit_event) in the PBO soon after first display of an editable ALV grid to register enter as an event to do validations on fields like qty. If user enters some character like 'abc' for qty and hits enter on keyboard, ALV grid pop's up a standard message ( I haven't coded for this.Since I use DDIC structure in field catalog, the Std. ALV program takes care of it. ). THis takes care of the validation before I click on save.
call method alv_grid->register_edit_event
exporting
i_event_id = cl_gui_alv_grid=>mc_evt_enter.
This works fine. But I want this validation to run when I also click the SAVE button of the screen. Is it possible to run this standard validation in my PAI event eg. SAVE ? I thought I will be, by calling the method check_changed_data in my PAI event. But this is doing nothing. Does this method conflict with register_edit_event or something ? So , basically what I am looking for is to trigger the event or call the method which does the same work as the "check" button on ALV grid.
Any advice or tips or sample code is greatly appreciated.
Thanks,
Shareen

Hi Shareen,
Handle the data_changed event in the grid.
Whenever you make changes in the data in ALV Grid this event would be triggered. Here you can perform additional validations that you may need to perform.
    METHODS handle_data_changed
      FOR EVENT data_changed OF cl_gui_alv_grid
      IMPORTING er_data_changed.
Implementation:
METHOD handle_data_changed.
    PERFORM validations USING er_data_changed.
ENDMETHOD.
FORM validations USING er_data_changed TYPE REF TO cl_alv_changed_data_protocol.
DATA: ls_good TYPE lvc_s_modi.
DATA wa LIKE LINE OF lt_good_cells.
CALL METHOD g_grid->register_edit_event
    EXPORTING
      i_event_id = cl_gui_alv_grid=>mc_evt_modified.
LOOP AT er_data_changed->mt_good_cells INTO ls_good.
    CASE ls_good-fieldname.
    WHEN 'FIELDNAME'. "Your fieldname
        CALL METHOD er_data_changed->get_cell_value "Get the changed value
          EXPORTING
            i_row_id    = ls_good-row_id
            i_fieldname = ls_good-fieldname
          IMPORTING
            e_value     = temp. "Your temp variable
        "Make your validations here.
    ENDCASE.
Ps: Reward points if helpful.

"CHECK_CHANGED_DATA" of the ALV Grid class

Hi Friends
I have an application in which I have created an editable ALV grid using CL_GUI_ALV_GRID.I have also registered the "ENTER" event of the class so that the method "CHECK_CHANGED_DATA" gets fired which in turn raises event DATA_CHANGED and looks then for any entries
in the error protocol.
The problem is in case of some values entered by the user the method "CHECK_CHANGED_DATA" is throwing a "Conversion Exit"(field too short) short dump.
To handle this error I need a method which fires before the "CHECK_CHANGED_DATA" and gives me all the values entered by the user on the screen.This way I will be able to trap the error.
Any suggestions are welcomed.

How can we find out data in an editable ALV grid has been changed or not?

Hi Experts,
How can we find out whether a data in an editable ALV grid has been changed or not.
I am using the
FM -> REUSE_ALV_GRID_DISPLAY_LVC
for ALV display.
I have to chekc whther data has been changed or not befor saving. if changed then only i want to
SAVE
. I cannot use the internal table comparison method for this purpose also i am not using OOP ALV.
So kindly sugest me an alternative.
Thanks and Regards,
Shahana

Hi,
Thanks for your answer. I already saw this post.
See this method.
CALL METHOD reuse_alv_grid->check_changed_data
IMPORTING
e_valid = lv_check.
This will update the internal table with the edited values. Then we can go for internal table comparison.
But my scenario will not allow me for itab comparisons.I just want to know the ALV data has been changed or not.

Shahana

Enter Key Event in Editable ALV Grid

Hi all,
I am trying to create and editable ALV grid using the REUSE ALV FM.
On the grid after changing a value, if I press enter key the pai is not triggered. I have tried the various example programs (BCALV*) but could not find anything relevant.
Basically I need similar functionality to normal module pool programming as in validations on screen done when enter key is pressed after screen entry.
Is it possible to capture the Enter keypress on the ALV grid?

Hello Preet
I can only tell you how I would solve this using the ALV grid control (CL_GUI_ALV_GRID) because I have abandoned using ALV function modules.
The problem with running through PAI is whether the focus (i.e. the cursor) is still on the control or already on the (surrounding) main program. If the control has the focus, you do not run through PAI.
I would add a "Refresh" button to the toolbar of the ALV list. Normally, this button is already there or you only have to make it visible.
When the user pushes this button you catch the corresponding user-command and call the CHECK_DATA_CHANGED method to see if values have been changed on the editable grid. If so, the previous method will fire event DATA_CHANGED.
Now, in the event handler method (e.g. HANDLE_DATA_CHANGED) you receive as input a data change object (CL_ALV_CHANGED_DATA_PROTOCOL). This object contains all changed values. These values you will need to make your checks.
I assume that the logic will be similar using ALV function modules.
Regards
Uwe

How to Transfer Data from editable ALV grid control to internal table?

Hi,
Can anyone give me a simple example by which I can transfer data from editable alv grid control back to the internal table. The ALV has been created by OO approach.
I would appreciate if the solution is provided without handling any events.
Regards,
Auro

Hello Auro
You simply need to call method <b>go_grid->check_changed_data</b> at PAI of the dynpro displaying the ALV grid. If data have been changed on the editable ALV grid then this method will raise event DATA_CHANGED. If you do not want or need to handle this event (e.g. for validating the edited values) then you do not define any event handler method.

Uwe

Edittable ALV grid using CL_GUI_ALV_GRID supported in ERP 4.7

Hi..
I like to know whether EDItable ALV grid is Supported in version 4.7 .....
..Thanks & Regards
Ashish

Hi..
1. To make the whole grid editable: pass EDIT field for layout structure(lvc_s_layo) as 'X', in this way your whole grid would be editable.
2. To make few fields editable: pass EDIT field for catalog(lvc_t_fcat) for the relevant fields as 'X', your grid with those relevant fields will be editable.
3. To make columns editable: This is bit tricky...you have to include a field with type LVC_T_STYL(this is a table type) in your internal table which is used for final display, you have to append all those fields in this table type field and pass the field style the value as "cl_gui_alv_grid=>mc_style_enabled"(this means making the field ediable)

Determining Duplicate Entries in Editable ALV Grid

Hopefully this question is not as obvious as it may seem at first. Thanks for any input or ideas...read carefully, it is not just a simple duplicate check with which I'm having a problem.
I have an editable ALV grid and I need to ensure that the user doesn't try to enter the same material number twice. I used the program BCALV_EDIT_03 and 04 as a model. I can tell if in my session a user is trying to put in the material number twice. Not a problem. I can also tell if the user is trying to add a material to the ones already on the grid that is a duplicate. That is not a problem either. Here is the catch...and I'd like to point out that BCALV_EDIT_04 has the same problem.
The user enters line 10 with material 0245 and line 20 with 0345. There is no duplicate. Then they say, 'Oooops, I got them backward' and then move 0345 to line 10 and 0245 to line 20. When you hit enter, the change handler says that line 10 and 20 were changed and the field MATNR was changed. It then compares the new fields to what is already in the grid...low and behold the grid already has these two entries and the protocol adds the error for both lines.
I will add the code here, but it is pretty much exactly as in BCALV_EDIT_04. If you want to see the error in that program execute it, put in two new lines with the same airline and two different dates and hit save. Everything is fine. Then swap the dates and hit Save again...it will say these are duplicates, which they are not...this program is not saving to the database. The only difference between mine and bcalv_edit_04 is that mine uses an 'ENTER' event and not a 'SAVE'.
I'm looking for good ideas on how to compare the two...the mt_good_cells (session active) and the grid itself to know when a user has 'moved' data. The current workaround is for the user to copy the line and then reapply it...but that seems a bit glitchy.
Thanks in advance, I appreciate any sage advice. : )

Runtime Error - TABLE_FREE_IN_LOOP in editable ALV GRID

While modifying editable ALV Grid, (CL_GUI_ALV_GRID) I am getting an unexpected dump as follows -
"Runtime Error TABLE_FREE_IN_LOOP".
In a Editable ALV grid whenever new row is added using standard append row button, And while saving, i check for any initial values, in that case iam displaying a warning message. So after that when i try to modify the row, and press enter key, Iam getting this dump "TABLE_FREE_IN_LOOP".
Can you please help on this regard.
Thanks in advance..
Best regards,
Prasad.

Hello Krishna
take a additional internal table which is exactly of same type of the internal table which you want to modify . try modifying the second internal table. and then proceed for db update(if required).

Urgent : Problem with Editable ALV Grid for Quantity and Currency Fields

Hi All,
I am using Editable ALV Grid display and have quantity and value as editable fields in the display.
When user changes these values these values are not changing properly .
For the quantity field the domain is MENG13 with 3 deciamal places and here if we enter 500 it takes it as 0.500 .
The same problem is for the currency field. Here the Domain is WERT7 with 3 decimal places.
Here also it takes last 2 digits after decimal places by default.
Please advice how to get proper values in this case from ALV editable fields.
Thanks and Regards
Harshad
Edited by: Harshad Rahirkar on Dec 25, 2007 7:39 AM

for all the currency field , it will display like that only.
u have to manipulate uin program before displaying.
if they are giving 500, in program multiply with 100 and move it to table.
when u are getting from table, divinde and display.
this is what I am doing.
Reward if helpfull.
