Hi Balaji,

      1). BAPI method

      2). Commit Method for committing the work

       3). Roll Back Method for reverting the command.

By using BAPI or method your creating any no.(ex. delivery num.) and it is created successfully then you have to commit the work then only that data will update into data base if suppose any errors happens then system itself won't store the data if requires you can use the Rollback method by using sy-subrc or by return parameter (or return table )

And we can see the errors by using the Return table or return parameters .

Thanks & Regards,

Hi,

   As per my knowledge , Bapiret2 will return the details like success as well as failure , etc..,

: S Success, E Error, W Warning, I Info, A Abort in TYPE.

based on that we can display the error messages by using type = 'E'.

basic:

loop bapiret2 into wa_ret2 where type = 'E'.

   write : wa_ret2-MESSAGE_V1 , wa_ret2-MESSAGE_V2.......

endloop.

like this.

this is only for basic we can display by using FM (log display Fm also).

Thanks & Regards,

Krishna

Hi,

You can normally check whether the BAPI has failed from the Importing parameter and the Return Table. Inorder the get the error occurred during the process, LOOP the return table ( Eg: which has a structure BAPIRET2 ) based on the TYPE field i.e. which displays the error type ( Eg. W - Warning , E - Error ).

This return table contains all the details as follows:

TYPE

ID

NUMBER

MESSAGE

LOG_NO

LOG_MSG_NO

MESSAGE_V1

MESSAGE_V2

MESSAGE_V3

MESSAGE_V4

PARAMETER

ROW

FIELD

SYSTEM

Note: You can use the where-used List for BAPI_TRANSACTION_ROLLBACK in your system for your reference.
