BBPS_PCHI_NODE 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 "Hierarchy Search Help for the Product Categories" 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_BBPS_PCHI_NODE TYPE BBPS_PCHI_NODE.
The BBPS_PCHI_NODE table consists of various fields, each holding specific information or linking keys about Hierarchy Search Help for the Product Categories data available in SAP. These include ID (Category ID), GUID (Category GUID), TREE_ID (Category GUID), TYPE (Not More Closely Defined Area, Possibly Used for Patchlevels)... 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. .
