Hi,

You can write it PBO.

Say your input /output field is ZZZ.

If ZZZ is initial.

Your select query.

ZZZ = your select query output.

endif.

Dear friend ,

You can write it PBO. By giving a module to check whether your input output field is empty or not . Suppose that your input/output field is A the you can write a select statement a = your select query .

Hello

You can also use a better way of validation

FIELD. and

CHAIN ENDCHAIN.

statement

Check standard program

DEMO_DYNPRO_FIELD_CHAIN

Hope this will help you

Thanks

Hi,

We write the validation in PAI, where we can check thr initiality and popup a message.

like:

if p_date is initial.
 p_date = sy-datum.
endif.

in your case it would be :

if p_parameter is initial.

select ...
from...
where...
into ....

endif.

example :

MODULE check_chain_300 INPUT.

  IF g_date_from > g_date.

    MESSAGE i051.

    LEAVE TO SCREEN 9000.

  ENDIF.

ENDMODULE.                 " check_chain_300  INPUT

thanx.
