Question in BDC session method.

YayatiEkbote — Fri, 10 Sep 2010 07:36:30 GMT

Hi guys,

I am trying to upload BOM using BDC session method.

While doing this, i have learnt the steps by heart. But i do not understrand the logic behind the steps. For example, why do we include this statement

Data: IT-BDC like BDCDATA occurs 0 with headerline.

What if we don't include this statement?

Hi Yayati,

Every BDC screen would capture in the standard structure.

In with following contends are

Field Name Description

PROGRAM BDC module pool

DYNPRO BDC Screen number

DYNBEGIN BDC screen start

FNAM Field name

FVAL BDC field value

This structure is populated during the BDC and posted using call transaction or Session method.

Hence The following statement define the internal table declaration of the same, the addition with header line would allow you to use that table as work area at the same time.

Data: IT-BDC like BDCDATA occurs 0 with header line.

So IT_BDC is workarea and IT_BDC[] is internal table.

Regards

Dhirendra

Hello Dhirendra,

Thanks for immediate reply. I want to understand BDC method conceptually. What exactly happens by performing each step.

I am putting up the BDC i made. I copied some of the code from here and there. It works fine but i don't understand the purpose of BDCDATA,

call transaction 'cs01'

and form bdc_dynpro and form bdc_field.

I am quite new to ABAP. Please don't mind if i ask dumb questions.

I am unable to understand how control flows through the code logic.
