Explain BDC. BDC stands for batch data communication is used to tranfer data from non sap system to sap system.
There are two method used 2 transfer data using BDC
1 DIRECT METHOD
2 BATCH INPUT METHOD it is also of two type :-
i) CALL TRANSACTION METHOD
ii) SESSION METHOD The major difference b/w call transaction and session method is that in call transaction method data is updated Synchronously but session method is asynchronously session is generated in session method but session is not generated in call transaction method BDC is all about automating the screen flow. for example, lets say we send an IDoc to external system using transcation we19. If the requirement is to automate it , then BDC can be used.
Procedure:
1. record the transaction with tcode shdb
2. copy the transaction recording program code from where you want to execute it
3. use the method to call : call transaction or session method The above are the ways to automate those screen flows for which recording is performed. Once you are done.. in the field values of BDC recording, put the values as input values whatever you want to mention. How to handle errors in call transaction method and session method. You can try this code to handle your BDC errors and display the corresponding error messages: if session ne 'X'.
call transaction tcode using itab_bdc mode 'N' UPDATE 'S' MESSAGES INTO i_errors. * N - no display
* E - errors only
* A - display ALL screens
elseif session = 'X'.
call function 'BDC_INSERT'

General flow of a BDC program is like this.... 1) First create recording for the T code which you want to make BDC for... Use T code SHDB for recording. 2 ) Now save that recording and create pogram from that recording using Create Program button. give the BDC driver program name and create. 3 ) Now the general logic of BDC program goes like this.... - Upload Flat file into and internal table using function module "UPLOAD"
- OPEN BDC GROUP.
- Now loop at that internal table which contains the data from flat file.
- move data from internal table to fields of BDCDATA using automatically gebnerated code from BDC.
- CALL TRANSACTION <T CODE> using BDCDATA...
- CLOSE BDC GROUP A sample program for the same is attatched here for your referance... just go through it.. report ztej_test_new no standard page heading line-size 255.

Requirement: Choose a transaction and write a Batch Input program with 'Call Transaction'. Do not use the Message tab feature of 'Call Transaction'. In this case the last error message will be at the SY-MSG* system fields. Recreate the complete error message from table T100! (This example is also used by the demonstration of SY-MSG* system fields) |

Move :- To assign the value of a data object <fl> to a variable < f2 >, use the following
statement:
MOVE < f1 > TO < f2 >.
or the equivalent statement
< f2 > = < f1 >.
The contents of < f1 > remain unchanged. < f1 > does not have to be a variable - it can also
be a literal, a text symbol, or a constant. You must always specify decimal points with a period
(.), regardless of the user's personal settings.
Multiple value assignments in the form
< f4 > = < f3 > = <f2 > = < f1 > .
Assign :- ASSIGN < f > TO < FS >.
When you assign the data object, the system checks whether the technical attributes of the
data object < f > correspond to any type specifications for the field symbol < FS >. The field
symbol adopts any generic attributes of < f > that are not contained in its own type
specification. Following the assignment, it points to < f > in memory.
