BDC Transcation Call

Hi Expert,

This is my code

lt_bdc-program = 'ZDT_SD_SALE_ORDER'.

lt_bdc-dynpro = '2000'.

lt_bdc-dynbegin = 'X'.

lt_bdc-fnam = 'BDC_OKCODE'.

lt_bdc-fval = 'SWITCH'.

APPEND lt_bdc.

CLEAR lt_bdc.

lt_bdc-program = 'ZDT_SD_SALE_ORDER'.

lt_bdc-dynpro = '2000'.

lt_bdc-dynbegin = 'X'.

lt_bdc-fnam = 'BDC_OKCODE'.

lt_bdc-fval = 'SEARCH'.

APPEND lt_bdc.

CLEAR lt_bdc.

lt_bdc-program ='ZDT_SD_SALE_ORDER'.

lt_bdc-dynpro = '0005'.

lt_bdc-dynbegin = 'X'.

lt_bdc-fnam = 'G_SO'.

lt_bdc-fval = itab-kdauf.

APPEND lt_bdc.

CLEAR lt_bdc.

lt_bdc-fnam = 'BDC_OKCODE'.

lt_bdc-fval = 'ENTER'.

APPEND lt_bdc.

CLEAR lt_bdc.

CALL TRANSACTION 'ZSD001' USING lt_bdc MODE 'A' UPDATE 'S'.

But when It display the zsd001, It display another dialog box which is like this

and I have press enter to go through each step.

How can I avoid this?

Thanks.
