hi,

i think u need to use the GET_CHANGED_DATA method in the CL_GUI_ALV_GRID class.

It will return the changed data.. Then u check the data and accordingly raise the error mess..

regards,

Hello Suresh

I assume that the editable field in your ALV list is defined as CHAR type in the underlying table (structure). In order to prevent non-numeric entries I would use the following approach:

• Define additional column for your ALV list, e.g.:

TYPES: BEGIN OF ty_s_outtab.
  INCLUDE type <name of z-table> AS data.
TYPES:  numfield(4)    TYPE n.  " Assumption: Your editable field is CHAR4, e.g. charfld
TYPES: END OF ty_s_outtab.
TYPES: ty_t_outtab  TYPE STANDARD TABLE OF ty_s_outtab WITH DEFAULT KEY.

DATA: gt_outtab TYPE ty_t_outtab. " your itab for ALV list

• Build fieldcatalog automatically and add additional column for NUMFIELD:

" Call fm LVC_FIELDCATALOG_MERGE with your z-table

  LOOP AT gt_fcat INTO ls_fcat
                            WHERE ( fieldname = <name of editable field> ).
     " Suppress this field
       ls_fcat-tech = 'X'.
       MODIFY gt_fcat FROM ls_fcat INDEX syst-tabix.


    " Modify LS_FCAT to reflect the additional NUMC4 field
      ls_fcat-fieldname = 'NUMFIELD'.
      ls_fcat-rolltype = ...  " change technical details from CHAR4 -> NUMC4

      ls_fcat-edit = 'X'.  " Now the NUMC4 field is editable

      INSERT ls_fcat INTO gt_fcat INDEX syst-tabix.
  ENDLOOP.

• Initial load of outtab: shuffle values from CHAR4 to NUMC4 field

REFRESH: gt_outtab.
  LOOP AT gt_data INTO ls_data.
    clear: ls_outtab.

    ls_outtab-data = ls_data.
    move ls_data-charfld TO ls_outtab-numfield.
    
    APPEND ls_outtab TO gt_outtab.
  ENDLOOP.

Hi Uwe,

I need your help regarding the following issue.

iam displaying report output using alvoops.

in the output list one of numc field is editable with length 4.

in field catalog i set lzero = 'X'. now output displaying with leading zeros.

now problem is if numc field doesnot contain any value out put displaying as '0000'.

i dont want '0000' and i want blank space in output list.

i want to edit alv grid for the numc field values like '0010','0009',0001and blank.

if i edit alv grid with numc value '0010' it showing only '10' doesnot consider leading zeros.

i want to validate the entered values for numc field.

Regards,

Suresh

TRY...

wa_Field_catalog-NO_ZERO = 'X'.

Cheers,
