ALV Edit - Required Fields

Is there an easy way to make a field required in the ALV grid? I have looked in the field catalog and the layout and can't seem to find a flag to set. Right now I am using "handle_data_changed" to check the required fields in the row. I think this should be a standard "feature" like it is on the table control.
Thanks in advance.

ALV edit (qty field is not convertable)

in my ALV program i have used one field MENGE (13,3) (QTY field) in the out put it is showing as 1.000,
when user going to enter a value (5) it is showing as 0.005 but user need it as 5.000.
please solve this question experts.....
Regards
Prasad.EV

hi venkatesh,
MENGE is QTY field,
instead of that u can give F (float) field then user can enter 5 it will be display 5.000.... that is best way to use it..
points please.. (if u have satisfied.)
Prasad.

Editing a field in ALV and validating the newly entered Value

Hi Experts,
   I have an ALV report in grid display (not object oriented). My requirement is to edit a field on the output and write the validations to validate the value that was edited on the ALV output.
This can be done using object oriented coding by using the method check_changed_data. For this to happen, i need to change the entire scope of my report into object oriented, which is like reinventing the wheel.
Since my report was developed using classical ABAP, what needs to be done to get this functionality. Any suggestions are welcome.
Thanks.

in the FM 'REUSE_ALV_GRID_DISPLAY' import parameter IS_LAYOUT check out the columsn EDIT and EDIT_COLUMN. Also Use FM 'REUSE_ALV_EVENTS_GET' to get list possible event and pass a subroutine name which will be called when ever event is fired.
example:
CALL FUNCTION 'REUSE_ALV_EVENTS_GET'
    EXPORTING
      i_list_type = 0
    IMPORTING
      et_events   = l_events.
READ TABLE l_events WITH KEY name = slis_ev_top_of_page
                               INTO g_event.
IF sy-subrc = 0.
    MOVE top_of_page TO g_event-form.
    APPEND g_event TO t_events.
ENDIF.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
      i_buffer_active    = 'X'
      i_callback_program = t_repid
      is_layout          = t_layout
      it_fieldcat        = t_fieldcat[]
      i_save             = t_save
      it_events          = t_events[]
    TABLES
      t_outtab           = g_editpos1[].

Editable ALV Quantity/Decimal field

Hi,
I have one column in ALV output which is editable .I have defined that in this way:
data :input type resb-bdmng.
fieldcatalog-fieldname = 'INPUT'.
fieldcatalog-seltext_m = ' Scrap'.
fieldcatalog-col_pos = fieldcatalog-col_pos + 1.
fieldcatalog-input = 'X'.
fieldcatalog-edit ='X'.
APPEND fieldcatalog TO fieldcatalog.
CLEAR fieldcatalog.
But if we edit the field in the output it gives error : " Too many decimal places ( maximum 0)"
If we add fieldcatalog-datatype = 'DECIMAL'. then it works fine but in that case it throws dump for toolbar button " Export to the local file " Its functinality is copied from standard interface SAPLKKBL program The dump is The current statement requires chaarater data type object .It cant take decimal fieldcatalogtype . If we remove fieldcatalog-datatype = 'DECIMAL'. then this button works fine but in this case the first error comes "Too many decimal places ( maximum 0)"
Please suggest how can I remove first error without setting fieldcatalog-datatype = 'DECIMAL'. property.
Will definetly ..... if its helpful

hi,
This is a common problrm when yu want to display the values in decimals...if the datatype is any other than character, if u try to export to file,it will throw dump.change the datatype into character in ur internal table itself ,,then calculte the values in decimals and insert to this fieldand display.Now it will allow edit and wont throw dump

How to make WD ALV Editable Fields (Cell) Mandatory (Obligatory) ?

Hello Friends,
I have requirement where I need to make WD ALV editable inputfield as Mandatory fields. I found out that there is no method available to do this.
If anybody has any solution then please reply to this thread.
Thanks,
Chandra

Hello Friends,
Thanks for your reply. I just wanted to elaborate more on this so that others will benefit from this thread.
I used method SET_STATE from class CL_SALV_WD_UIE_A_INPUT which is super class for class CL_SALV_WD_UIE_INPUT_FIELD.
The code looks as below,
Data:    lr_input_field     TYPE REF TO cl_salv_wd_uie_input_field.
        CALL METHOD lr_input_field->set_state
          EXPORTING
            value = cl_wd_abstract_input_field=>e_state-required.
well, I just forgot to check super class and its available methods...But got clear hint from Tulasi.
Thanks to all.

Is it possible to create a editable pdf with validation(required field) using Adobe Acrobat pro version?

Hi,
the subject says it all. I have downloaded the trail version to see if its possible to create a editable pdf with validation(required field) using Adobe Acrobat pro version?
Basically, I will have to create a pdf form where users fill it and send it back to me. there will be required fields (the textbox and check box) that user need to fill before saving the editable pdf?
Is it possible. if so, can someone kind enough to point to me right directions?
Thanks in advance.

Thanks for reply. What I am trying to achieve is to give an option for the user to download the pdf form and once the user tries to save the pdf, it validates with the required field. I managed to create the editable pdf with required fields option. I just need that validation to be done when user click on save file. How can I achieve this? thanks so much for your help.

Required field check in ALV

Hi,
I'm trying to make a required field check on a ALV field. I can see that the function works as required and produces an error to display in the message_manages
but when I return to the program no error is shown and no red box is displayed arround the field.
Any help is welcome...
Thanks,
Kris
This is my code:
DATA: l_attr_list TYPE cl_wd_dynamic_tool=>t_check_mandattr_tab,
             l_attr       TYPE cl_wd_dynamic_tool=>t_check_mandattr_struct,
             errors       TYPE boolean.
l_attr-node_path = 'QUOTATION_TO_CREATE'.
l_attr-element_index = 0.
l_attr-attribute_name = 'KWMENG'.
APPEND l_attr TO l_attr_list.
errors = cl_wd_dynamic_tool=>check_mandatory_attributes(
      attribute_list   = l_attr_list
      display_messages = abap_true
      context_root     = wd_context
CHECK errors EQ abap_false.

Hi Hans,
What ever you said is not possible because while returning to your program, the data won't be saved and it will closed in any situation.
If you want to do like this, Please display the pop-up before you are going to Program saying that " Do you want to save this data?" that time it will display the error and you can do what ever you want.
I think My answer will give helpful information to you. If not please reply with some more information then i will try to reslove your problem
Warm Regards,
Vijay

Dear experts,
I have an ALV with many lines.

Please help.
Thanks,

Hi again,
1. Just for info purpose.
2. We can use colours
3. Not only the full row color,
we can also manipulate the color in each cell.
4.
IMPORTANT THINGS
a. Extra field in internal table
clr TYPE slis_t_specialcol_alv,
(this field will contain the colour codes)
b. assign fieldname to alv layout
alvly-coltab_fieldname = 'CLR'
c. work area for colour
DATA : clrwa TYPE slis_specialcol_alv.
d. Populating the color
Once again
Loop at ITAB.

clrwa-fieldname = 'FIELDNAME'. "<--- FIELDNAME FOR COLOR
clrwa-color-col = 6. <------- COLOUR 0-9
APPEND clrwa TO itab-clr.

endif.

5. just copy paste in new program

ALV Editable not working

Hello Abapers,
I am not getting the desired output as per example.
I have followed all the steps as per the example but still a looser can anyone help me in this.
When I execute the program I get the following run time error
Field symbol has not been assigned.
I tried commenting the subroutine call
1} perform Change_fieldcatalogue and fetch data.
and i was getting the 2 custom container (top, bottom) on the screen output this time.
I have also created a screen 600 with all the attributes.
But i have doubt with this statement
Create a Custom container and name it CCONT and OK code as OK_CODE.
Save check and Activate the screen painter.
I hope on the layout screen the one which says custom control is only the custom container but i see that the fct code box is not highlighted then how can i assign a fctcode.
Could you plz also clear this.
Thanks in advance.
