Hi,

If you want to have selection screen at run time then just try out this piece of dynamic programming.

REPORT ZUTIL_SEARCH_STRUCTURE MESSAGE-ID 031 .

START-OF-SELECTION.

PERFORM DYNAMIC_CODE.

FORM DYNAMIC_CODE.

APPEND 'REPORT ZSEARCH NO STANDARD PAGE HEADING.' TO ITAB.

APPEND 'TABLES : DD03L,DD02L.' TO ITAB.

DATA TAB LIKE TEXTPOOL OCCURS 0 WITH HEADER LINE.

APPEND 'SELECTION-SCREEN BEGIN OF BLOCK BLK' TO ITAB.

APPEND 'WITH FRAME TITLE TEXT-001.' TO ITAB.

DO P4 TIMES.

REC_CNT = SY-INDEX.

CONDENSE REC_CNT NO-GAPS.

IF P1 = 'X'.

CONCATENATE 'PARAMETERS:F' REC_CNT

' LIKE DD03L-FIELDNAME OBLIGATORY.'

INTO WA.

APPEND WA TO ITAB.

TAB-ID = 'S'.

CONCATENATE 'F' REC_CNT INTO WA.

TAB-KEY = WA.

CONCATENATE'$$$$$$$$' 'Field Name' REC_CNT INTO WA.

TAB-ENTRY = WA.

ENDIF.

IF P2 = 'X'.

CONCATENATE 'PARAMETERS:D' REC_CNT

' LIKE DD03L-ROLLNAME OBLIGATORY.'

INTO WA.

APPEND WA TO ITAB.

TAB-ID = 'S'.

CONCATENATE 'D' REC_CNT INTO WA.

TAB-KEY = WA.

CONCATENATE'$$$$$$$$' 'Data Element' REC_CNT INTO WA.

TAB-ENTRY = WA.

ENDIF.

IF P3 = 'X'.

APPEND 'SELECTION-SCREEN BEGIN OF LINE.' TO ITAB.

CONCATENATE 'SELECTION-SCREEN COMMENT (15) FOR FIELD DT'

REC_CNT '.' INTO WA.

APPEND WA TO ITAB.

CONCATENATE 'PARAMETERS:DT' REC_CNT

' LIKE DD03L-DATATYPE OBLIGATORY.'

INTO WA.

APPEND WA TO ITAB.

CONCATENATE 'SELECTION-SCREEN COMMENT (16) FOR FIELD SIZE'

REC_CNT '.' INTO WA.

APPEND WA TO ITAB.

CONCATENATE 'PARAMETERS:SIZE' REC_CNT

' LIKE DD03L-LENG OBLIGATORY.' INTO WA.

APPEND WA TO ITAB.

APPEND 'SELECTION-SCREEN END OF LINE.' TO ITAB.

TAB-ID = 'S'.

CONCATENATE 'DT' REC_CNT INTO WA.

TAB-KEY = WA.

CONCATENATE'$$$$$$$$' 'Data Type' REC_CNT INTO WA.

TAB-ENTRY = WA.

APPEND TAB.

TAB-ID = 'S'.

CONCATENATE 'SIZE' REC_CNT INTO WA.

TAB-KEY = WA.

CONCATENATE'$$$$$$$$' 'Len. of Field' REC_CNT INTO WA.

TAB-ENTRY = WA.

ENDIF.

APPEND TAB.

ENDDO.

APPEND 'SELECTION-SCREEN END OF BLOCK BLK.' TO ITAB.

ENDFORM. " DYNAMIC_CODE

hi Jagath ,

thank you very much for help.

I don't understand how do you use this code.

How I'm suppose to use table itab and tab?

their contains all the necessary code to build a selection screen but how should I use it?

Hi Joseph,

Basically the idea is :

a) To create a new program at runtime

b) Generate your selection-screen at runtime

c) Execute your runtime-created program

Personally never used it. The only doubt for me in the FM's that you have mentioned is, how is it going to handle validation, if at all , there are any.

Thanks a lot for sharing these FM's with us.
