There are many APIs to send emails programmatically, but you should prefer CL_BCS class as said in note 190669 for sending lists via SAPconnect using the BCS interface:

As of Release 6.10, we recommend that you no longer use the API1 interface for sending documents. Instead, use the BCS interface.
Compared to the API1 interface, the BCS interface is easier to use since it is no longer required to fill a packing list. In addition, it offers more options (for example, setting any sender).
People have often many issues with the packing list, this parameter is difficult to understand, as binary should be stored in text parameter.

  • Class CL_BCS (the BCS interface), to be used since release 6.10
  • Older function modules:
    • SO_NEW_DOCUMENT_ATT_SEND_API1 is now a wrapper of SO_DOCUMENT_SEND_API1, so simply prefer to use SO_DOCUMENT_SEND_API1
    • There are also these function modules that some people use:
      • EFG_GEN_SEND_EMAIL, but it is not released and cannot send to multiple recipients
      • SO_DOCUMENT_REPOSITORY_MANAGER, but it is not released

The email is not sent immediately but collected, either SOST transaction has to be used to release them, or you can call RSCONN01 program.

Moreover, these APIs may also be used to send fax, SMS, or even send message only to Business WorkPlace (SAP integrated office, SBWP transaction).

Before being able to send mails, SAPconnect must be configured, using SCOT transaction.

What is the simplest code to send an email?

Use this wiki. It is based on CL_BCS, but you don't need to know how object-oriented ABAP works.

How to build lines of more than 255 characters?

With CONTENTS_TXT parameter, lines can have a maximum of 255 characters. You should pass the text as binary as explained in this wiki.
Principle: fill a unique string of characters with lines separated by cl_abap_char_utilities=>cr_lf character, then call function modules SCMS_STRING_TO_XSTRING then SCMS_XSTRING_TO_BINARY (you may also simply call the static method CL_BCS_CONVERT=>STRING_TO_SOLIX) to turn your string into an internal table of type SOLIX_TAB. Pass it to CONTENTS_HEX parameter.

How to prove that the email has been sent?

Use put_in_outbox = 'X' parameter of SO_NEW_DOCUMENT_ATT_SEND_API1, Check if RECEIVER-RETRN_CODE = 0 or not after the function module, Also check if the exception DOCUMENT_NOT_SENT is being raised or not, SCOT customizing INT enter domains to which u can send mail.

What is RFC_MAIL?

This is a C program installed on SAPGUI that you can call to send a simple mail to one person. You cannot enter any subject. This program is not supported by SAP, it could be removed at any time. ABAP statement: CALL FUNCTION 'RFC_MAIL' DESTINATION 'LOCAL_EXEC' EXPORTING user = '' TABLES mail = lt_textitab[].

How to enter tabulation character?

Use CL_ABAP_CHAR_UTILITIES=>HORIZONTAL_TAB. In non-unicode systems before 6.10, use data tab type x value '09' et concatenate 'text' tab 'text2' into text.

Mails are not sent

When you use the APIs, they are only collected. Either use SOST transaction to send them manually, or from program: submit rsconn01 with mode = 'INT' with output = ' ' and return.
It may be best to schedule a job with program RSCONN02 every 10 minutes when SAP system produces many mails.

Mails are no more sent after migration from 4.6C (or before) to 6.10 (or after, ECC5 or ECC6 for example)

You must add parameter COMMIT_WORK = 'X' when calling SO_NEW_DOCUMENT_SEND_API1

Note 873845 - HTML code in binary form cannot be read

Text document was incorrectly changed from system code page to recipient code page (set in SOST), though it was already in recipient code page. From SAPKP70005, SAPKB62057, SAPKB64016, SO_NEW_DOCUMENT_ATT_SEND_API1 has been changed to wrap SO_DOCUMENT_SEND_API1 exactly. The CONTENTS_HEX parameter should be now used for binary attachments.

Documents are no longer readable after upgrade TO 620

See Note 787418 - Sent documents are not readable after upgrade. Corrected in SAPKB62053, SAPKB64013, SAPKB70003.

The email contains 'P R I N T I N G' instead of 'PRINTING'

Pass email text using CONTENTS_TXT parameter instead of CONTENTS_BIN

The sent appointment doesn't work

There is a recent note: Note 1353329 - iCalendar document that is sent is processed incorrectly

SAP template programs

SAP provides the following programs, which are in fact templates because they can't be executed as is (email is hardcoded for example):

  • BCS_EXAMPLE_1: send a simple text provided as an internal table of text lines to
  • BCS_EXAMPLE_2: send a simple text provided as an internal table of text lines and text attachment in form of text lines itab to fax DE 09999-123456
  • BCS_EXAMPLE_3: send a simple text provided in an internal table of text lines and an additional note to SY-UNAME
  • BCS_EXAMPLE_4: send a simple text provided in an internal table of text lines recipients are selected in dialogue (default
  • BCS_EXAMPLE_5: a simple text provided in an internal table of text lines and an attached MS word document provided in internal table SOLIX_TAB (document retrieval has to be coded) to
  • BCS_EXAMPLE_6: enter customer, carrier (flight demo data) and email, and generate corresponding FP_TEST_03 adobe form, and send it as attachment to the email
  • SENDLIST_BCS: provided as attachment in SAP Note 190669 - Sending lists using SAPconnect, it uses SO_DOCUMENT_SEND_API1
  • SENDLIST_BCS: provided as attachment in SAP Note 190669 - Sending lists using SAPconnect, it uses CL_BCS
  • ZSSO_DOCUMENT_SEND_API1_46 and ZSSO_DOCUMENT_SEND_API1_610: provided as attachment in SAP Note 609696 - SAPoffice: Error in documentation (SO_DOCUMENT_SEND_API1). There are 2 versions, one for 4.6C, and one for 6.10 and above, the difference between the 2 is only the addition of COMMIT_WORK parameter for 6.10 version. Both call SO_DOCUMENT_SEND_API1.

ALV output in PDF format

The principle is to print ALV to spool directly, convert spool to PDF, and build and send the mail. Can be used in background


  • Activatable (plus) means that code can be activated on all NetWeaver solutions (ECC, CRM, SolMan, etc.)
  • Works immediately (plus) means that you don't need to change the program (because of hard-coded email for instance), nor create customizing or data, except SAP flight demo data that you should have initialized on your system (see wiki Flight Data Application - Demo Example for Integration Technologies). If the code is to be created using several manipulations like creating a function module or a global class, it's slow, so only a (warning) is granted.
  • Only a mail demo (plus) means that the article only deals with sending mails

  1. Hello,

    i am looking a way for sending a pdf document as an email body not as an attachment.

    Any ideas?



  2. Former Member


    I am using SO_DOCUMENT_SEND_API1 to send mail to many customers (as selected by user on the screen interactively) with an attachment and a fixed sender name as for example successfully.

    The requestor whose address is wants to see that all the sent items should also be recorded in his sent items box in outlook.

     Is this possible in ABAP?

    Thank you


  3. Former Member


    I used CL_BCS class concept for sending email through background.

    Most of the time the mail is sending correctly but sometimes it fails.

    When i saw the job in SM37, i found the message : Exception condition  "CNTL_ERROR" raised.

    Can you please guide me at this point.

    Thanks in advance.





  4. Hi!

    Both  SO_NEW_DOCUMENT_SEND_API1 and CL_BCS->SEND transform valid HTML to invalid HTML (for example, transforming <span></span> to <span/>). Why? How to avoid this this?



  5. Hi all.


    Could anyone explain how to send a mail to Outlook Distributed List (not to SAP DL created in so23 etc, just to external already crated list) by CL_BCS

    My DL is in *@sap,com domain, and this domain is included into SMTP settings. I can send a mail to particular participant of DL, but not to entire DL. 

    Everytime i receive a message:

    • No delivery as sender or receiver address is invalid

    Delivery to person works fine.



    Possible reason/solution may be described here
