Question

what are the common errors we wil get in BDC?

Answer 1

hi sunil
BDC errors are similar to what you get in online transaction. Suppose you enter an invalid material number in online ME21N ( create Po ) system will throw an error and you have to correct it by chnaging a valid material number . Same error you can get in BDC as well. It is very difficult to generalize types of error as errors will depend on the transacation you are doing.
However some of the common BDC errors are ( Data for Screen Not Found, Field Not available in Screen ). These again are transaction specific and you have to analyze it by calling the transacion in display ALL mode.
The errors you get depends upon the transaction you are
running.
This is how you handle:
Let's consider you are recording for the transction CJ40
(Messages table declaration )
DATA :BEGIN of t_msg occurs 0.
include structure BDCMSGCOLL.
DATA END of t_msg.
Handling it :
CALL TRANSACTION 'CJ40' using T_BDCDATA MODE 'N' UPDATE 'S' MESSAGES INTO t_msg.
commit work.
If you want to display the errors in the screen you can use a function module named 'RPY_MESSAGE_COMPOSE'
This gives you the corresponding message for the message number that you input.
Below is the sample code
Loop at t_msg. " Messages internal table
w_msgid = t_msg-msgid.
w_msgno = t_msg-msgnr.
w_msgv1 = t_msg-msgv1.
w_msgv2 = t_msg-msgv2.
w_msgv3 = t_msg-msgv3.
w_msgv4 = t_msg-msgv4.
CALL FUNCTION 'RPY_MESSAGE_COMPOSE'
EXPORTING
LANGUAGE = SY-LANGU
MESSAGE_ID = w_msgid
MESSAGE_NUMBER = w_msgno
MESSAGE_VAR1 = w_msgv1
MESSAGE_VAR2 = w_msgv2
MESSAGE_VAR3 = w_msgv3
MESSAGE_VAR4 = w_msgv4
IMPORTING
MESSAGE_TEXT = t_text-text.
TABLES
LONGTEXT =
EXCEPTIONS
MESSAGE_NOT_FOUND = 1
OTHERS = 2
IF SY-SUBRC <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
MESSAGE_TEXT contains the message.
