Hi Kartik,

If 'am not wrong, you are changing the Selection screen fields as 'Success' and displaying the paths, after the execution of the report?

If so, Export the selection screen fields values to SAP memory, and when the user presses the 'Back' button, Import it back from the memory and fill he Selection screen fields.

Hope this will help you.

Thanks & Regards

Hi Kartik,

the first requirment is simple, as Manu said, set SAP memory or handle ' at selection screen output' event is OK.

but " when user wants when clicks back button on selection screen after selection screen dynamically changes then selection scrren fields should be same values. " , this is difficult to implement, except you create another screen to be called in this program.

Maybe have other solution, hope i can help you.

Hi karthik,

As of my knowledge,i  tried your requirement through the following sample program.. Check it once it is useful to u.

REPORT  ZCC.

DATA:
       lv_file                  type string.
SELECTION-SCREEN BEGIN OF BLOCK b2 WITH FRAME TITLE text-001.
PARAMETERS: p_fpath      TYPE ibipparms-path OBLIGATORY,   "Input file path
             p_logf       TYPE string OBLIGATORY,           "Log file path
             p_trun       AS CHECKBOX DEFAULT 'X'.
SELECTION-SCREEN END OF BLOCK b2.

*For getting F4 Help to p_fpath.
*For getting F4 Help to p_fpath.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_fpath.
   CALL FUNCTION 'F4_FILENAME'
     IMPORTING
       file_name = p_fpath.

START-OF-SELECTION.
lv_file = p_fpath.
WRITE:/ lv_file.
MESSAGE 'Success' TYPE 'S'.
set PF-STATUS 'ZSAT'.

at USER-COMMAND.
   CASE  sy-ucomm.
     when 'BACK'.
       submit ZCC VIA SELECTION-SCREEN.
   ENDCASE.

hi,

the basic is that we write all the validation codes for the selecction screen parameter under the event

at selection screen, u can use at selection screen on block and also for individual fields.

This will be the first event trigerred before going to start of selection where ur actual process will start.

So if any errors are found it wont proceed to start of selection and displays the messge in the selection screen itself.

So if u r using oops concept then u can call the funciton to create the file in  at selection screen and display what ever message u want to. You can make this method static so that you dont have to create any object in the at selection screen
