In newer versions of SAP (newer than 6.10 release) best practice is to send emails using BCS interface instead of API1 interface. BCS interface is easier to use than the older API1 interface. Plus you are not required to fill the packing list which makes it less complicated.
These function modules can be used to send email in older versions.
These functions could be replaced by ABAP class CL_BCS (Business Communication Service).
How to handle Email Queues in SAPConnect Send Request (SOST).
When you trigger emails using these FMs or CL_BCS ABAP OO class, queues get generated under SOST (SAPconnect Send Requests). SOST queued emails can be processed using program RSCONN01 (SAPconnect: Start Send Process).
Set correct parameters such that you do not send out unwanted messages and affect the performance of the servers.
Also these messages can be sent manually using transaction SOST.
ABAP Program to Send Emails using ABAP OO Class CL_BCS.
When using class CL_BCS to send emails there are few basic steps which should be considered. Depending on the email format and attachment type parameter should be set differently.
In the shown example email is send in HTML format with a text file (.txt) attachment. Email subject, body, recipient email and text for attachment are given in the selection screen.
As we are using HTML email format, body text in selection should be converted to HTML format. When attaching TXT or any other attachments to email, attached data should be converted to “SOLIX” format which is accepted by BCS class. Attachments can be text files, PDF files, world documents etc.
Setting email subject, HTML email body and initializing.
Convert Data Formats.
Converting attachment string to xstring, converting xstring to SOLIX format and calculating attachment size.
Adding email recipients and finally pushing the email to SOST.
Please leave a comment if you have any queries on CL_BCS class, email driver program or SOST.
Hi, I am Isuru Fernando, Senior SAP Integration Consultant with 10 years of SAP full-cycle implementation and support project experience.
From the early days, I had a passion for coding, software development, and everything tech-related. I started my carrier as an ABAP developer and soon found my love for system integration when I learned SAP XI 3.0 in 2008. Playing a variety of roles from an offshore technical consultant (ABAP, PI/PO, BW, BOBJ) at the beginning of my career to a technical lead managing a team of consultants in different countries, I have gained immense experience in SAP project implementation life cycle.
Having the opportunity to work on SAP implementation projects in USA, EU, and Asia, I learned valuable ins and outs of global business processors in Sales and Distribution (SD), Material Management, Retail, Customer Relationship Management (CRM), and Finance and Controlling (FICO).
Through this blog, I want to share my expertise in SAP technical areas such as SAP ABAP, PI/PO, AIF, and Basis. I also want to provide a platform for others with similar ambitions who would like to share their SAP technical expertise with the world!
