[Beginner] Transferring parameters between Pages

[guillaume-hrc]

Hi,

It is my first BSP Application.

I have troubles transferring parameters from one page to the other. It seems that nothing is transferred at all !

My BSP application is : <b>Stateful</b>

It has 2 pages :

start.htm

report.htm

In the OnInputProcessing handler, I use these statements to pass on data from <i>start.htm</i> to <i>report.htm</i> :

        navigation->set_parameter( name = 'LAUNCH_DATE' value = w_launch_date ).
        navigation->set_parameter( name = 'LAUNCH_TIME' value = w_launch_time ).

        navigation->next_page( 'TOREPORT' ).

Besides, my Page attributes in <i>report.htm</i> (which has the 'TOREPORT' navigation request) are defined as follows :

<b> Name Auto Typing Assoc. Type Description</b>

LAUNCH_DATE X TYPE D Date of launch

LAUNCH_TIME X TYPE T Time of launch

Please, could you see what is missing ??

Thanks in advance.

Cheers,

Guillaume

Thanks for you recommendations !

Actually, it seems that what was preventing<i> report.htm</i> to get the values of the attributes was the Type. Indeed, I declared them as <b>Type D</b> and <b>Type T</b> whereas the set_parameter automatically converts them into <b>STRING</b>.

Therefore, I declared them as STRING and I add this bit of code and everything goes well now !

DATA : w_launch_date     TYPE d,
       w_launch_time     TYPE t.

*_ Convert Date attribute
CALL FUNCTION 'CONVERT_DATE_TO_INTERNAL'
  EXPORTING
    date_external            = launch_date
  IMPORTING
    date_internal            = w_launch_date
  EXCEPTIONS
    date_external_is_invalid = 1
    OTHERS                   = 2.
IF sy-subrc <> 0.
  w_launch_date = sy-datum.
ENDIF.

*_ Convert Time attribute
CALL FUNCTION 'CONVERT_TIME_INPUT'
  EXPORTING
    input                     = launch_time
  IMPORTING
    output                    = w_launch_time
  EXCEPTIONS
    plausibility_check_failed = 1
    wrong_format_in_input     = 2
    OTHERS                    = 3.
IF sy-subrc <> 0.
  w_launch_time = sy-uzeit - 10.
ENDIF.

Thanks again.

Hi Guillaume,

Try giving <b>toreport</b> instead of TOREPORT as navigation request. Let us know if it works.

HI Guillaume,

To pass the parameters you don't have to make the application stateful.

Please try doing the following changes.In onInputProcessing

<b>navigation->goto_page( 'report.htm' ).</b>

instead of navigation->next_page( 'TOREPORT' ).

Also ensure that in the second page(report.htm),the page attributes LAUNCH_DATE and LAUNCH_TIME should be checked to AUTO .

Hope this helps,

Regards,
