IF_WD_SELECT_OPTIONS

[Former Member]

Hi All,

I have created some Inputfields in Two Tabstrips via method of if_wd_select_options like this Coding below and set parameter obligatory true.

How can I achieve Error Messages if User has not given a Value in this Mandatory Field and want to change Tabstrip? Is there Methods to do it and pls give some Coding. Thanks!

wd_this->mr_selopt->add_selection_field( i_id = 'INP_CHARGABLE_ORDER'

I_DESCRIPTION

= wd_assist->CHARGABLE_ORDER_TXT

I_OBLIGATORY

= abap_true

I_MEMORY_ID

= 'AUN'

I_NO_EXTENSION

= abap_true

I_NO_INTERVALS

= abap_true

I_VALUE_HELP_TYPE

= IF_WD_VALUE_HELP_HANDLER=>CO_PREFIX_SEARCHHELP

I_VALUE_HELP_ID

= 'ZAUF' "'VMVA'

it_result

= lt_range ).

hi beserithan.......

you can make use of the method GET_VALUE_OF_PARAMETER_FIELD in the interface if_wd_select_options. it returns the value of your parameter. check for the value. if itis not there.... just generate an error message using the code wizard.

Hello Alex,

is there no other possibility for this, which is triggered by Interface?

hi bserithan...

you have to do your checking manually.....

and this is one of the easiest ways.

be little more clear for better solution.

Beserithan,

You can check for the presense of error messages by calling method check_selection_screen or any of the other check methods.

Hi Thomas,

sorry for lately Reply. What do you mean with check methods?

Hello Beserithan,

Interface IF_WD_SELECT_OPTIONS has three methods starting with CHECK_. As said above, calling method CHECK_SELECTION_SCREEN returns the number of error messages thrown by the SelectOptions component. If the number was greater than zero, the user did something wrong.

Best regards,

Thomas
