A Comprehensive Guide to Sending Emails with Multiple Attachments in IFS ERP

Introduction:

In the world of IFS ERP, many people are familiar with the basic functionality of sending emails through the command_sys.mail functionality. However, there is a whole range of powerful methods available within the command_sys API that often go unnoticed. In this blog post, we will explore one such function that allows us to send multiple attachments. When we refer to attachments, we mean various file types, such as PDFs, images, or any other data that can be stored in the database as a Blob.

Sending Multiple Attachments using command_sys API:

The command_sys API offers a wealth of features, and one particularly useful function is the ability to send emails with multiple attachments. This functionality empowers users to include various files alongside their emails, enhancing the communication process and enabling a more comprehensive exchange of information. Whether you need to share important documents, images, or any other file type, this feature can simplify the process and streamline your workflow.

The versatility of Attachment Types:

When we mention attachments, it's important to note that they can encompass a wide range of file types. From PDFs that capture detailed reports or invoices to images that provide visual representations, the command_sys API supports handling diverse attachment formats. Additionally, these attachments are stored in the database as Blobs, allowing for efficient storage and retrieval.

Understanding the Process of Sending Multiple Attachments:

To send emails with multiple attachments through the command_sys API, there is a specific procedure you need to follow. This procedure involves appending all the attachments to an Oracle record that is linked to a nested table named "attachment_arr." Fortunately, the command_sys package has already defined all the necessary steps. You simply need to call an additional procedure to append your Blob or Clob to the nested table type.

Step-by-Step Guide to Sending Mail with Multiple Attachments:

To send mail with multiple attachments using the command_sys API, follow these steps:

Step 1: Define the Oracle nested table:
Before you can proceed, it is important to define the Oracle nested table. This table will be responsible for holding the attachments that you wish to include in your email.

Step 2: Call the Add_Attachment procedure:
Next, you need to call the standard procedure, Add_Attachment. This procedure has three parameters: the Blob or Clob content of your attachment, the file name, and the nested table to which you want to add the attachment. By passing these parameters, the content will automatically be added to the specified variable of the nested table.

Step 3: Invoke the main mail procedure:
After adding the attachments to the nested table, you can proceed to call the main procedure named "mail" of type "attachment." This procedure will handle the sending of the email with the appended attachments.

Sample Code for Implementing the Procedure:
To help you create your own procedure for sending emails with multiple attachments, consider the following code snippet:

```sql
DECLARE
  -- Non-scalar parameters require additional processing 
  attachments_ COMMAND_SYS.ATTACHMENT_ARR;

  CURSOR get_data IS 
    SELECT blob_data, file_name FROM your_table; 
BEGIN
  -- Call the procedure
  FOR rec_ IN get_data LOOP 
    Command_sys.Add_Attachment(attachments_, rec_.file_name, rec_.blob_data);
  END LOOP; 

  COMMAND_SYS.Mail(
    sender_ => :sender_,
    from_ => :from_,
    to_list_ => :to_list_,
    cc_list_ => :cc_list_,
    bcc_list_ => :bcc_list_,
    subject_ => :subject_,
    text_ => :text_,
    attachments_ => attachments_,
    mail_sender_ => :mail_sender_
  );
END;
```

Conclusion:

While many users are familiar with the basic mail-sending functionality in IFS ERP, 
the power of the command_sys API often remains untapped. By utilizing the API's robust methods, such as the ability to send multiple attachments, you can significantly enhance your communication capabilities within the ERP system. Whether you need to share important documents, images, or any other file type, the command_sys API provides a versatile solution for efficient and effective communication. By following the step-by-step guide outlined in this blog post, you can leverage the power of the command_sys API to streamline your workflow and elevate your email communication to new heights.
