Normally BAPI's will retun you an internal table with RETURN table, which will have the list of message it encountered while processing the BAPI.

Then you need to loop at that internal table to build the messages, you can use messagetextbuild FM to build the messages.

Hi,

Normally u avoid exceptions in BAPI.

Use internal table ; Populate the error if any and return the internal table.

Hi Kiran,

There is no explicit condition or any BAPI or FM to handle the errors. It has to be done manually, the same procedure we use in BDC programs after CALL TRNSACTION and getting the messages into the Internal Table.

Assume I am using <b>BAPI_QUOTATION_CREATEFROMDATA2</b> for creating quotations(Transaction VA21).

I called the BAPI and got the following error messges in my <b>RETURN</b> table.

<b>TYPE |ID                  | NUMBER| MESSAGE</b>
E   |VP                  |112   |Please enter sold-to party or ship-to party
E   |V4                  |219   |Sales document  was not changed     

So based on this you have to determine your error handling.

Something like this after calling the BAPI.

  READ TABLE return WITH KEY id     = 'VP'
                             number = '112'.
  IF sy-subrc  = 0.

* Your error handling

  ENDIF.

You can use the BAPI_MESSAGE_GETDETAIL to get the detailed error messages. Refer to the table T100 for exporting parameters.

Hi,

All BAPIs contains Return table as table parameter. This table is populated with error messages/Sucessful messages after BAPI was executed.

Please check this table for any error messages.
