Hey gurus,

In Interactive ALV if i click for first time on any line in the first grid display,

second screen is displaying correctly...with line items.But when i click on back button and if click on the same line again the same line tems are displaying again..

waht may be the problem?..

For Ex:

ist scree.

vbeln vkorg kunr

4355 0001 1234

if click on this line..in the second scree.

matnr posnr netpr

p-001 0001 450

So after clicking on back button on the standard tool bar

matnr posnr netpr matnr posnr netpr

p-001 0001 450 p-001 0001 450

Hi,

If SY-UCOMM = 'BACK'.

Refresh the Itab or fields which you are storing and displaying in the secondary list

ENDIF.

Thanks.Even then it is not working.

See the code:

FORM USER_COMMAND USING R_UCOMM LIKE SY-UCOMM RS_SELFIELD TYPE SLIS_SELFIELD.

CASE R_UCOMM.

WHEN '&IC1'.

READ TABLE IT_VBAK INTO WA_VBAK INDEX RS_SELFIELD-TABINDEX.

DATA: ID LIKE SY-TABIX.

ID = RS_SELFIELD-TABINDEX.

PERFORM BUILD_CATALOG_VBAP.

PERFORM GET_DATA_VBAP.

PERFORM DISPLAY_VBAP_DATA.

WHEN 'BACK'.

REFRESH J_FIELDCAT.

REFRESH IT_VBAP[].

ENDCASE.

ENDFORM.

hi,

I can see that you are doing a read in a work area wa this is not defined in the form if it is defined in the screen module this behaves like a global variable in which case you will have to clear it. Also you subroutine does not have any parameters so you might be using global tables or work areas clear these in the double click even &ic1.
