Hi all,

Could you please explain me this BDC program logic flow?

data : begin of bdc-data occurs 100.

include structure bdcdata.

data ; end of bdc_data.

perform dynro using :

'X' 'SAPLMGMW' '0100',

'' ' 'bdc_cursor' 'msichtausw-dytxt(07)',

' ' rmmw-matnr' p_matnr, (~user input)

..........

call transaction 'mm42' using bdc_data mode 'A'.

form dynpro using dynbegin name value.

clear bdc_data.

if dynbegin eq 'X',

move: name to bdc_data-program,

value to bdc_data-dynpro,

'X' to bdc_data-dynbegin.

else.

move : name to bdc_data-program,

value to bdc_data-fval.

endif.

append bdc_data.

end form.

My main concerns is what is the structure of bdcdata and how 'X' is realted to bdc_data-dynbegin.

Thanks in advance.

Will reward if useful.

Your answers

1) Structure of BDC data is :

PROGRAM : Name of the program associated with screen.

DYNPRO : Number of screen.length(4). set this for the first record for the screen.

DYNBEGIN: indicates the first record for the screen.Length(1).

set this field to X only for the first record i.e it indicates that it is Start of a new screen number

FNAM : name of the field.Length(35).

FVAL : value of the field. length(132).

2) how 'X' is realted to bdc_data-dynbegin ? (Answer is marked in bold above)

Mark if helpful

hi,

in BDC, we can perform validations on legacy data by using MAPPING logic.

in mapping logic we use structure having name BDCDATA.

fields of BDCDATA structure are....

BDCDATA-program-----> means module pool program which we r used in BDC.

BDCDATA-dynpro-------> means currentl active screen, for which screen we are

going to pass data.

BDCDATA-dynbegin----> means is the initial or default screen,default vale for this

field is 'X'.

BDCDATA-fnam----

> field name which we are used in validations.

BDCDATA-fval----

>field value which we are used in validations

the BDCADAT table comntains records, which are supported by SAP data type, form this table we pass data into data base tables by using transaction.

Ashokreddy.

hi,

BDCDATA: it is a structure .it contains the components

PROGRAM-BDC module pool

DYNPRO-screen number

DYNBEGIN-screen start('X')

FNAM-Field name

FVAL-BDC field value.

USED TO TRAVERSE IN THE TRANSACTION MODULEPOPL.

how 'X' is realted to bdc_data-dynbegin.

it indicates Start of a new screen number
