Hi,

Did you clear the internal table?

Did you use APPENDING... table anywhere.

Hi,

Try to free the container before you leave the screen.

g_container->free( ).

I hope this helps.

Hi Suganya,

Refresh your Itab first..

in select statement are you using

select * into table or Appending table..

in either case use

REFRESH itab.

before..

Hi Suganya,

Then try to clear all your fieldcatalogs...

Before building it...

Or can you display your code...

Re: ALV List

Former Member — Thu, 09 Mar 2006 10:30:43 GMT

Hi Suganya,

Are you using Block_List_Append..or

if the table has duplicate entries..

just use

sort itab.

delete adjacent duplicates ..

before calling ALV

Hi,

you can refresh the ALV list by calling

REFRESH_TABLE_DISPLAY method of CL_GUI_ALV_GRID.

call this method in PBO.

syntax

DATA : WA_LVC_S_STBL TYPE LVC_S_STBL.

CALL METHOD G_GRID->REFRESH_TABLE_DISPLAY

EXPORTING

IS_STABLE = WA_LVC_S_STBL

Hope this helps..

Hi Suganya,

Thanks for your esteemed reply...

I tried and made the neccessaryu changes...

Just clear gt_fieldcat[] in FORM BUILDPROJECT as follows...

<b>
FORM BUILDPROJECT.
* DATA FIELD CATALOG
* Explain Field Description to ALV
DATA: FIELDCAT_LN TYPE SLIS_FIELDCAT_ALV.
CLEAR GT_FIELDCAT[].</b>

It works now.
