DPR_HIERNO 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 "Interface: Elements of a Hierarchy" 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_DPR_HIERNO TYPE DPR_HIERNO.
The DPR_HIERNO table consists of various fields, each holding specific information or linking keys about Interface: Elements of a Hierarchy data available in SAP. These include NODENAME (Name of the hierarchy node), TLEVEL (Level of a hierarchy node), LINK (Link indicator for a hierarchy node), PARENTID (Parent ID for a hierarchy node)... 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. .
