STR_TECH_HEADER 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 "Structure: Equipment General Data" 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_STR_TECH_HEADER TYPE STR_TECH_HEADER.
The STR_TECH_HEADER table consists of various fields, each holding specific information or linking keys about Structure: Equipment General Data data available in SAP. These include OBJECTTYPE (Type of Technical Object), AUTHGRP (Technical object authorization group), TXT04 (User Status)... 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. .
