parameters checkbox at selection screen

[madalinacorina_floca]

hello all,

I have a problem that I don't know how to solve:

I will put my program here:

the problems are with selection-screen block 2.

so, I have 4 checkboxes: 3 for class and one for invoice.

when I hit the business class checkbox I need to bring all the flights for business class. And so on for the other 2.

for the invoice, when I hit the check box for invoice, I need to bring all the flights that have invoice flag.

TABLES: spfli.

 CLEAR: p_cb_b , p_cb_e.

 CLEAR: p_cb_b , p_cb_f.
 ENDCASE.

and the invoice parameter I used it here:

after all the data from select data and joins ..

 LOOP AT lt_schedule INTO ls_schedule.

READ TABLE lt_scarr INTO ls_scarr WITH KEY carrid = ls_schedule-carrid
 BINARY SEARCH.
 IF sy-subrc = 0.

 gs_flights-carrname = ls_scarr-carrname.

 ENDIF.
 READ TABLE lt_sbook INTO ls_sbook WITH KEY carrid = ls_schedule-carrid
 connid = ls_schedule-connid
 BINARY SEARCH.
 IF sy-subrc = 0.

gs_flights-invoice = ls_sbook-invoice.

 IF p_cb_inv IS NOT INITIAL.
 gs_flights-invoice = ls_sbook-invoice.

 IF ls_sbook-invoice <> 'X'.
 CONTINUE.
 ENDIF.
 ENDIF.
 ENDIF.

 IF sy-subrc = 0.
 READ TABLE lt_stravelag INTO ls_stravelag WITH KEY agencynum = ls_sbook-agencynum
 BINARY SEARCH.
 ENDIF.

can anyone tell me what have I missed, because no checkbox work as it should.

thank you all,

Please edit your question, select your code and press the button [CODE], which makes the code appear colored/indented, it will be easier for people to look at it. Thank you!

Please debug your code, and you'll see the problem.

Hi,

Try using At selection screen event which triggers at PAI. Make sure all the checkboxes are having correct values before START-OF-SELECTION. Please check if you can directly use these flags in database tables while fetching the entries. Also, for the class checkbox if only one is possible at a time, replace them with radio button.

Thanks!
