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

Editable ALV- Quantity field value is getting changed while double clicking

Hi all,
I have created Editable ALV grid using Class concepts. Quantity field is editable in dat. but after changing value and if im double clicking on that field, value is getting changed. eg: 45 is changing to .045. How can i resolve this problem.
Could u plz help.

Hi Anu,
One question from my side.
U have displayed the ALV.In that grid u have quantity field.U have changed the value of that field to 45.
When u press enter the value has been changed to .045.Is this u r problem.
U can do onething anu.
Declare one varaible with the local field.
Pass u r quantity field value into that variable.
While displaying thriugh SET_TABLE_FIRST_DISPLAY in your internal table pass this variable.
It will solve u r problem.I think.
Let me if yu have any problem
IF u want u can refer to the program BCALV_EDIT* in se38.
There also u have needful info
Thanks,

Editable ALV Quantity problem

Hi all,
In Editable ALV quanity fields store wrong result .
Quanity is of packed type with 3 decomals.
For eg - During display like quanity is 22.245 when i insert quantity like 9 then it makes .009.
Any suggestion welcome.

Hi Navdeep singh
Specify the number of decimal places for that field in field catalogue. So that your problem will be resolved.

I get error message DB745 with EDIT ALV on a field type DEC?

Hi,
I have an ALV which has a field type DEC.
The ALV is open for edit.
Once I put negative number in, I get the error message DB745.
This error is retrieved from SAP code and I do not see any reason why.
I checked the field cat and it looks fine (ref to a field type DEC).
I am using lcl_grid_event_receiver with method: handle_data_changed FOR
EVENT data_changed OF cl_gui_alv_grid.
In that method I get the error in er_data_changed->mt_protocol.
There is no problem to show negative data if it is saved in the database
as negative.
Can anyone throw ideas how to fix that?
Thanks,
Itay

If you simply check the domain WERT7, you'll see that the checkbox for "Sign" is not checked. Therefore negative numbers are not allowed.
Just because a field is decimal or currency does not mean that negatives are allowed.
Many times, the sign is handled by a separate debit/credit indicator field such as a field with a domain of SHKZG.

Row id in editable ALV while using MP_MOD_ROWS

Hi Experts
I have an editable alv with 13 fields editable in it. Inside the DATA_CHANGED event i am making use of the attribute MP_MOD_ROWS for doing some specific validations. But I am not able to pass the row_id to the the mehod add_protocal_entry while multiple rows are in MP_MOD_ROWS ,since its not available MP_MOD_ROWS .
Can anyone tell me how i can get the row_id for each row in MP_MOD_ROWS.
Since I need the full row for validations , i cant use MT_MOD_CELLS.

I do not understand your question about row_id as this is a component lvc_t_modi table. I don't know MP_MOD_ROWS as there is only attribute MT_MOD_ROWS of parameter ER_DATA_CHANGED of event DATA_CHANGED of CL_GUI_ALV_GRID.

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.

Editable alv not update with decimal values

Friends.
i have editable alv, there is a editable field is with 3 decimal places.
my problem is when i changed there value as 15 its take 1.5 and if i change as 150 its take 15.
can you please help me to solve my problem?
thanks in advance!

Hi Friend,
This Problem will be solved in below method.
Define Your filed type in currency.
Eg. vnumber TYPE CE1SAS1-KWABLK (kwablk is a currency field).
In FIELDCATALOG add currency.
Eg:
lw_fcat-fieldname = 'VNUMBER'.
lw_fcat-edit = 'X'.
lw_fcat-datatype = 'CURR'.

Editable ALV - how to throw an error message for a specific line & field

Hi all,
I've implemented an editable ALV and also the ON_DATA_CHECK event to check the values, entered in the ALV. So this works fine and I can check the values.
But now, I want to throw an error message corresponding to the field in the ALV, where the error occured.
How can I throw this error message corresponding to a specific line/field in the ALV?
I was using REPORT_ATTRIBUTE_ERROR_MESSAGE and REPORT_ELEMENT_ERROR_MESSAGE but without success.
I'm also using a loop over the "CHANGES" in the ALV and within this loop, I use
elem_alv = node_alv->get_element( index = <change>-element_index )
to get the element for the message.
CALL METHOD lo_message_manager->REPORT_ELEMENT_ERROR_MESSAGE
EXPORTING
 MESSAGE_TEXT = 'my message'
 ELEMENT = elem_alv
* ATTRIBUTES =
* PARAMS =
* MSG_USER_DATA =
* IS_PERMANENT = ABAP_FALSE
* SCOPE_PERMANENT_MSG = CO_MSG_SCOPE_CTXT_ELEMENT
* MSG_INDEX =
* CANCEL_NAVIGATION =
* IS_VALIDATION_INDEPENDENT = ABAP_FALSE.
2.) is it right, that for an editable ALV, I can't use the WDDOBEFOREACTION to do the checks?
If I try to use this, I can't get the values of my ALV table to check it.
Thanks,
Andreas

Hi Andreas,
I have tried to replicate your problem and I am getting the desired output. I have a row by name TEMP_NEW in my ALV and I want to throw an error message whenever the user enters a value of 4 for that particular field. Please find my coding as below. The important thing is where we perform the actual comparison between the r_value and 4. r_value is defined in SALV_WD_S_TABLE_MOD_CELL as reference to type DATA. So suppose the user enters a value of say 3 in the TEMP_NEW field of the ALV then r_value would contain 3 but if you observe its type in debugging mode it would be as TYPE REF TO I and not TYPE I. So you cannot directly say something like:
"if ls_modified_cells-r_value = 3" as this would lead to a syntax error. Define a field-symbol say <temp> and then use it to get the actual value into it by saying like:
ASSIGN ls_modified_cells-r_value->* TO <temp>.
Then you can use this <temp> for comparison in your IF statement like:
IF <temp> = 3.
Find the entire coding as below:
METHOD check_data.
DATA: lr_node TYPE REF TO if_wd_context_node,
 lr_element TYPE REF TO if_wd_context_element,
 ls_modified_cells TYPE salv_wd_s_table_mod_cell.
FIELD-SYMBOLS <temp> TYPE data.
" get message manager
DATA lo_api_controller TYPE REF TO if_wd_controller.
DATA lo_message_manager TYPE REF TO if_wd_message_manager.
lo_api_controller ?= wd_this->wd_get_api( ).
CALL METHOD lo_api_controller->get_message_manager
 RECEIVING
 message_manager = lo_message_manager.
lr_node = wd_context->get_child_node( name = 'NODE' ).
LOOP AT r_param->t_modified_cells INTO ls_modified_cells.
 lr_element = lr_node->get_element( index = ls_modified_cells-index ).
 IF ls_modified_cells-attribute = 'TEMP_NEW'.
" Get the value extracted into the field symbol from the reference variable
 ASSIGN ls_modified_cells-r_value->* TO <temp>.
" Use the value present in this field-symbol for your comparison
 IF <temp> = 4.
" report message
 CALL METHOD lo_message_manager->report_attribute_error_message
 EXPORTING
 message_text = 'Sample message text'
 element = lr_element
 attribute_name = ls_modified_cells-attribute.
 ENDIF.
 ENDIF.
ENDLOOP.
ENDMETHOD.
Hope this helps resolve your problem.

A question about editing ALV fields

Hello Expert,
In my project, we need to read data from DB and display in the ALV. In the ALV output, we should be able to edit the records, and after user clicks the "Save" button in the applicaiton toolbar, the program should be able to save the changed data into DB.
Currently, I can display the data in ALV and all fields are editable. After I change some data and click "Save", the program will go into subroutine 'F_ALV_USER_COMMAND', but the data in the internal table GT_OUTTAB is not changed.
I generate the ALV output by the following calling:
call function 'REUSE_ALV_GRID_DISPLAY'
      exporting
        i_callback_program = wf_pgm
        is_layout          = gs_layout
        it_fieldcat        = gt_fieldcat[]
        i_callback_pf_status_set     = 'F_PF_STATUS_SET'
        i_callback_user_command = 'F_ALV_USER_COMMAND'
        is_variant         = g_variant
      tables
        t_outtab           = gt_outtab
      exceptions
        program_error      = 1
        others             = 2.
In the subroutine 'F_PF_STATUS_SET', I call a GUI Status defined by myself.
But if I call as below
call function 'REUSE_ALV_GRID_DISPLAY'
      exporting
        i_callback_program = wf_pgm
        is_layout          = gs_layout
        it_fieldcat        = gt_fieldcat[]
       i_callback_pf_status_set     = 'F_PF_STATUS_SET'
        i_callback_user_command = 'F_ALV_USER_COMMAND'
        is_variant         = g_variant
      tables
        t_outtab           = gt_outtab
      exceptions
        program_error      = 1
        others             = 2.
GT_OUTTAB is changed accordingly after clicking the "Save".
Can any expert tell me why Internal table is not changed in the case I use user-defined GUI Status?
Thanks & Regards, Johnny

Quan field editable alv

HI,
Ive made an editable alv using my z-table. The z-table has a field sqty which is of type 'QUAN' referring to 'sunit' field(type UNIT) of same ztable .
Whenever i try to edit this sqty field it behaves weirdly. If i enter 123456 value in sqty , it takes it as 123.456 , or if i enter 1 in sqty it takes it as .001.
Why does it divide by 1000 always. IS it something to do with unit conversion? how do i overcome this problem.
I also had written a program to upload in this table using flat file, that program works fine.
Can anyone guide me please.
Bye

Hi,
There is a conversion routine attached to the Unit field. ( Conversion routine -CUNIT). Check in output characteristics of the domain.
One of the ways is to clone the domain and datatype and use them without the conversion routine.
Hope it helps.
Thanks,
Saipriya
