To check and validate the external

data, user dialog is simulated

through an SAP transaction

(i.e., an online program).

BDCDATA Structure

To simulate user dialog,

you must know the

following information:

(1) online program name,

(2) screen numbers,(3) field names, and

(4) field values.

The BDCDATA ABAP/4Dictionary structure is used

in a batch input program to

collect this information for

an entire transaction.

For our example, we

will use the ChangeVendor transaction

(FK02) to add a street

address to an already

existing vendor.

Step #1Use System > Status

menu path to determine

online program name

(SAPMF02K), screen

number (0106), andtransaction code (FK02).

Step #2Use F1 key and Technical

Info pushbutton in each

screen field to be filled to

determine the field name.

Step #3

Determine how to proceed

in the transaction

(go to the next screen by

pressing the Enter key).

Field name = RF02K-LIFNR

Field name = RF02K-D0110

After researching the transaction,

we can determine the contents of

the BDC table.



Declaring BDC Table

DATA: BDC_TAB LIKE BDCDATA

OCCURS 6 WITH HEADER LINE.

The internal table used to collect the

transactions information must be

declared LIKE BDCDATA.



Filling BDC Table - Method #1

FORM FILL_BDC_TAB.

REFRESH BDC_TAB.

CLEAR BDC_TAB.

BDC_TAB-PROGRAM = SAPMF02K.

BDC_TAB-DYNPRO = 0106.

BDC_TAB-DYNBEGIN = X.APPEND BDC_TAB.

CLEAR BDC_TAB.

BDC_TAB-FNAM = RF02K-LIFNR.

BDC_TAB-FVAL = TEST1.

APPEND BDC_TAB.

CLEAR BDC_TAB.

BDC_TAB-FNAM = RF02K-D0110.

BDC_TAB-FVAL = X.

APPEND BDC_TAB.

CLEAR BDC_TAB.

BDC_TAB-PROGRAM = SAPMF02K.

BDC_TAB-DYNPRO = 0110.

BDC_TAB-DYNBEGIN = X.

APPEND BDC_TAB.

CLEAR BDC_TAB.BDC_TAB-FNAM = LFA1-STRAS.

BDC_TAB-FVAL = 123 Main St..

APPEND BDC_TAB.

CLEAR BDC_TAB.

BDC_TAB-FNAM = BDC_OKCODE.

BDC_TAB-FVAL = /11.

APPEND BDC_TAB.

ENDFORM.



Filling BDC Table - Method #2

FORM FILL_BDC_TAB.

REFRESH BDC_TAB.

PERFORM POPULATE_BDC_TAB

USING:

1 SAPMF02K 0106,

RF02K-LIFNR TEST1,

RF02K-D0110 X,

1 SAPMF02K 0110,

LFA1-STRAS 123 Main St.,

BDC_OKCODE /11.

ENDFORM.

FORM POPULATE_BDC_TAB USINGFLAG VAR1 VAR2.

CLEAR BDC_TAB.

IF FLAG = 1.

BDC_TAB-PROGRAM = VAR1.

BDC_TAB-DYNPRO = VAR2.

BDC_TAB-DYNBEGIN = X.

ELSE.

BDC_TAB-FNAM = VAR1.

BDC_TAB-FVAL = VAR2.

ENDIF.

APPEND BDC_TAB.

ENDFORM.

This two-subroutine method to fill the BDC table is preferable because the

POPULATE_BDC_TAB subroutine is reusable throughout all batch input programs.
