CIFVBXBDIN 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 "VBX: Internal Selection Data for Header" 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_CIFVBXBDIN TYPE CIFVBXBDIN.
The CIFVBXBDIN table consists of various fields, each holding specific information or linking keys about VBX: Internal Selection Data for Header data available in SAP. These include DELPS (MRP element item), SELECTION (Selection ID, (Persistent) Copy of VBX_SEL_ID), POSEX (Position ID, Copy of VBX_POS_ID)... See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
