CVIS_EI_SMTP is a standard SAP Structure so does not store data like a database table does. It can be used to define the fields of other actual tables or to process "Ext. Interface: E-Mail Addresses" Information within sap ABAP programs. This is done by declaring abap internal tables, work areas or database tables based on this Structure. These can then be used to store and process the required data appropriately. i.e. DATA: wa_CVIS_EI_SMTP TYPE CVIS_EI_SMTP.
The CVIS_EI_SMTP table consists of various fields, each holding specific information or linking keys about Ext. Interface: E-Mail Addresses data available in SAP. These include DATA (), STD_NO (Standard Sender Address in this Communication Type), E_MAIL (E-Mail Address), EMAIL_SRCH (E-Mail Address Search Field)...
