bdcdata

[Former Member]

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.

Hi

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.

<b>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</b>

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

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

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

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.

<b>fields of BDCDATA structure are....</b>

<b>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</b>

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.

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
