ITSHTRCOBJ 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 "ITS language resource" 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_ITSHTRCOBJ TYPE ITSHTRCOBJ.
The ITSHTRCOBJ table consists of various fields, each holding specific information or linking keys about ITS language resource data available in SAP. These include THEME (ITS topic of an application)... 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. .
