DATA : I_BDCDATA LIKE BDCDATA OCCURS 0.
EXPLAIN ABOUT THE bdcdata???

Hi Balaji,
BDCDATA is a structure which consists of these fields for the processing of a transaction. So we have to declare an internal table of BDCDATA to store all this data.
BDCDATA fields:
PROGRAM -> Name of the Program
DYNPRO -> Screen No
DYNBEGIN -> At the start of a new screen we have to set it to 'X' or else ' '.
FNAM -> Name of the Screen field where data has to be entered
FVAL -> Value for Screen field
Thanks,

hi,
BDCDATA-DYNBEGIN describes the default or intial screen of the transaction which was used in BDC.
BDCDATA is the structure used for mapping logic( means move the cursor position from internal table work area to specified apllication and specified screen).
form bdc_dynpro using program dynpro.
clear bdcdata.
bdcdata-program = program. "MODULE POOL PROGRAM NAME
bdcdata-dynpro = dynpro. " CURRENT ACTIVE SCREEN
bdcdata-dynbegin = 'X'. ' DEFAULT SCREEN
append bdcdata.
endform.

Hi Balaji,
BDCDATA stores the values of the screen while populating.
and also it consists of details like ..which screen from which program the process should be started.
Suppose you have a loop like this
DATA: bdcdata LIKE bdcdata OCCURS 0 WITH HEADER LINE.
loop at it_final.
CLEAR bdcdata.
REFRESH bdcdata.
PERFORM bdc_dynpro USING 'SAPMP50A' '1000'.
PERFORM bdc_field USING 'BDC_OKCODE'
'=COP'.
PERFORM bdc_field USING 'RP50G-PERNR'
it_final-pernr. "'4317'.
CALL TRANSACTION 'PA30' USING bdcdata.
endloop.
----
Start new screen *
----
FORM BDC_DYNPRO USING PROGRAM DYNPRO.
CLEAR BDCDATA.
BDCDATA-PROGRAM = PROGRAM.
BDCDATA-DYNPRO = DYNPRO.
BDCDATA-DYNBEGIN = 'X'.
APPEND BDCDATA.
ENDFORM.
----
Insert field *
----
FORM BDC_FIELD USING FNAM FVAL.
IF FVAL <> NODATA.
CLEAR BDCDATA.
BDCDATA-FNAM = FNAM.
BDCDATA-FVAL = FVAL.
APPEND BDCDATA.
ENDIF.
ENDFORM.
Above includes are available in include BDCRECXX.

DYNBEGIN -> At the start of a new screen we have to set it to 'X' or else ' '.
FNAM -> Name of the Screen field where data has to be entered
FVAL -> Value for Screen field
remember to clear the internal table (BDCDATA) before calling the transction .
