Automatically populating the search help values into different fields on the selection screen by using search help exit
By Krishna Chaitanya Gogineni, Deloitte Consulting
I have a selection screen with some
fields. For scheduling agreement field I have given the F4 help by using search
When user clicks on F4 for scheduling
agreement, in the search results along with the scheduling agreement I’m
giving Item, date, and some other fields.
Now, the requirement is when ever user
selects a scheduling agreement from F4 help I need to populate the corresponding
item automatically from the search help on to the Item field on the selection
In the above screen shot if I select
30000018 and click enter, corresponding item (000020) should get populated into
the Item field on the selection screen.
After displaying the search help
values, when CALLCONTROL-STEP = ‘RETURN’ we need to call the function module
IF callcontrol-step = 'RETURN'. DATA : i_dynp TYPE STANDARD TABLE OF dynpread. DATA : w_dynp TYPE dynpread. w_dynp-fieldname = 'S_POSNR-LOW'. w_dynp-fieldvalue = gv_posnr. APPEND w_dynp TO i_dynp. CLEAR : w_dynp. CALL FUNCTION 'DYNP_UPDATE_FIELDS' EXPORTING dyname = 'SAPMZKLIM_HUREPORT' dynumb = '0300' request = 'A' TABLES dynpfields = i_dynp EXCEPTIONS invalid_abapworkarea = 1 invalid_dynprofield = 2 invalid_dynproname = 3 invalid_dynpronummer = 4 invalid_request = 5 no_fielddescription = 6 undefind_error = 7 OTHERS = 8. IF sy-subrc <> 0. * MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO * WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4. ENDIF. EXIT. ENDIF.
When I select the agreement,
corresponding item (20) will get populate into item field in the selection
