WebDynpro Select options sign,options field not cleared

[Former Member]

Hi,

I have a Webdynpro report with selection screen with select-option fields and ALV output. This report works perfectly when it is executed for first time. I have a back to selection screen button in ALV output. When I click on this , I get the first screen using outbound plug which is connected to inbound plug of first screen.

But , when I execute the report after coming back from ALV output and removing some select-option input values, it gives wrong output. When I debugged,it is found that Sign and option values in the selection screen is not refreshed from screen and program reads the tables with a value 'I EQ space'. How can I resolve this issue ? I don't want to clear all selection screen field values when coming back from ALV screen. How can I refresh the select-option  SIGN and OPTION fields from screen ?

Thanks in advance ,

Hi Varughese,

Here is the sample code to clear Select options

DATA lo_componentinterface TYPE REF TO if_wd_component_usage.
DATA lo_interfacecontroller TYPE REF TO iwci_wdr_select_options .
DATA lo_r_helper_class TYPE REF TO if_wd_select_options.

lo_componentinterface = wd_this->wd_cpuse_ZSELOPT( ).

lo_interfacecontroller =   wd_this->wd_cpifc_ZSELOPT( ).

lo_r_helper_class = lo_interfacecontroller->init_selection_screen( ).

CALL METHOD lo_r_helper_class->reset_all_selection_fields.

Thanks & Regards,

Store the selection fields in attributes or context.

second time you can compare the old values and new values, so that, you can clear when space is entered.

before executing, update context with recent selection values

Hi All,

All these are workaround to resolve the issue. I would like to know the root cause of the issue ? Is it a known issue ? or am I doing something wrong ?

Request your valuable feedback on this issue.

HI Varughese,

So when you come back from the ALV , you cleared some select options , still the sign and option remains with empty low and high values right?

IF so please write code in On_action results or some thing relavent with logic

get the selction options table and loop and check if there are any records with low and high as null but the option and sin are present , if you find so please delete the record and at last attach the table to the node again.

But there is a chance that user want to search with value 'space' . How can I know user has really wanted to search with value space ?

Thanks,

Raise a pop up asking user if empty value space is available in Select options.

If they agree keep it other wise remove it..

Hi

Try RESET_SELECTION_FIELD of IF_WD_SELECT_OPTIONS.

It will reset the range table for the selection field.

Hi Swati,

Thanks for the reply.

RESET_SELECTION_FIELD will clear the field, but I want to keep the values entered in the selection screen for the first run when come back from second screen.

Hi,

Couldn't you simply invalidate the context?
