/AIN/DM_DEV_STR 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 "Device" 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_/AIN/DM_DEV_STR TYPE /AIN/DM_DEV_STR.
The /AIN/DM_DEV_STR table consists of various fields, each holding specific information or linking keys about Device data available in SAP. These include DEV_ID (Device ID), DEVGRP_GUID (Device Group GUID), DEV_DESCR (Device Description)... 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. .
