ABAP学习（15）:邮件发送实例
ABAP邮件
使用ABAP程式可以发送外部邮件。
Tcode:SOST可以查看邮件发送队列以及邮件发送状态。
1、使用类对象发送邮件
类CL_BCS:发送邮件功能类，创建发送邮件请求，添加发送人，添加收件人，添加发送内容等；
类CL_DOCUMENT_BCS:邮件内容类；
类CX_BCS：发送异常类；
接口IF_RECIPIENT_BCS:邮件地址接口；
邮件发送过程：
1、使用CL_BCS=>CREATE_PERSISTENT( )创建邮件发送请求,cl_send_mail保存对象；
2、使用CL_DOCUMENT_BCS=>CREATE_DOCUMENT( )，创建发送内容对象，cl_content保存类对象；
3、添加附件，使用cl_content->add_attachment，调用内容对象方法add_attachment；
4、将发送邮件内容添加到请求对象，cl_send_mail的SET_DOCUMENT方法；
5、调用发送请求的SET_SENDER方法设置发件人；
6、调用发送请求对象的ADD_RECIPIENT方法设置收件人；
7、调用发送请求对象的SEND方法发送邮件；
附件生成：
使用XML文本，最后保存为excel，获得excel类型附件。实际上就是构建一个EXCEL的XML文档。可以将一个EXCEL保存成XML格式文件，就可以看到我们需要构建的XML文档样子。
1、使用cl_xml=>create( ),创建IF_IXML类对象，XML工厂；
2、使用XML工厂生成文档模型对象，使用create_document( )方法；
3、使用create_simple_element，创建各种子节点；
4、使用create_namespace_decl，生成namespace;
5、使用set_attribute，设置节点属性值；
6、使用set_attribute_node，为节点设置属性节点；
Excel样式：
对应XML样式：其中以下节点是必须要生成的
1、生成Workbook节点；
2、生成Worksheet节点；
3、生成Table节点；
4、生成Row节点；
5、生成Cell节点；
6、生成Data节点；
EXCEL对应的XML文档，红色部分是必须生成节点。

步骤0：定义全局参数
"内表数据 DATA:lt_spfli LIKE TABLE OF spfli. DATA:ls_spfli LIKE LINE OF lt_spfli. "正文内容 DATA:lv_text TYPE string. DATA:lt_main_text TYPE soli_tab. "html轉換string DATA:lv_html_str TYPE string. "附件內容 DATA:t_solix TYPE solix_tab. DATA:wa_solix TYPE solix. "附件内容字节长度 DATA:lv_bytecount TYPE sood-objlen.
步骤1：获取要发送表格数据，保存到内表 lt_spfli
FORM get_data. SELECT * INTO CORRESPONDING FIELDS OF TABLE lt_spfli FROM spfli WHERE carrid = 'AA'. ENDFORM.
步骤2：利用xml形式创建excel附件,这种方式有奇怪xls,xlsx兼容问题，将内容保存到t_solix内表

2、调用function发送邮件
使用function，‘SO_NEW_DOCUMENT_SEND_API1’发送邮件。
示例：
DATA:temp_spfli LIKE TABLE OF spfli WITH HEADER LINE. START-OF-SELECTION. PERFORM get_data. PERFORM send_mail. END-OF-SELECTION. FORM get_data. SELECT * INTO CORRESPONDING FIELDS OF TABLE temp_spfli FROM spfli WHERE carrid = 'AA'. ENDFORM. "send mail FORM send_mail. DATA: MAILSUBJECT TYPE SODOCCHGI1.
