Catch values for a Field exit for fields of the same dynpro
I want to catch the values of some other fields of the same dynpro besides de field im doing a Field Exit. Does anyone knows if this is possible or i have to think in another way to fill the field?
I've try to put some parameters in the function module but i obtain a short dump when i run the transacction cause de función in the standart program doesn't recognize the extra parameters besides INPUT or OUTPUT
Any clue will be great.

Yes you can get the value of the other field in the same screen by using the FM DYNP_VALUES_READ.
and here is how its supposed to be used.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR S_VERID-LOW. IT_DYNPREAD-FIELDNAME = 'S_MATNR-LOW'. APPEND IT_DYNPREAD. IT_DYNPREAD-FIELDNAME = 'S_WERKS-LOW'. APPEND IT_DYNPREAD. CALL FUNCTION 'DYNP_VALUES_READ' EXPORTING DYNAME = sy-cprog DYNUMB = sy-dynnr TABLES DYNPFIELDS = IT_DYNPREAD . IF SY-SUBRC <> 0. * MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO * WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4. ENDIF. READ TABLE IT_DYNPREAD INDEX 1. IF SY-SUBRC = 0. L_MATNR = IT_DYNPREAD-FIELDVALUE. ENDIF. READ TABLE IT_DYNPREAD INDEX 2. IF SY-SUBRC = 0. L_WERKS = IT_DYNPREAD-FIELDVALUE. ENDIF. TRANSLATE L_MATNR TO UPPER CASE. TRANSLATE L_WERKS TO UPPER CASE. SELECT VERID WERKS MATNR INTO TABLE IT_VERID FROM MKAL WHERE MATNR = L_MATNR AND WERKS = L_WERKS.
Hope this helps
