BBPS_FORMS_OUTPUT 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 "Form as E-mail Attachment or Letter" 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_BBPS_FORMS_OUTPUT TYPE BBPS_FORMS_OUTPUT.
The BBPS_FORMS_OUTPUT table consists of various fields, each holding specific information or linking keys about Form as E-mail Attachment or Letter data available in SAP.
