ESH_S_MU_NODE_ROLE 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 "Node Roles" 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_ESH_S_MU_NODE_ROLE TYPE ESH_S_MU_NODE_ROLE.
The ESH_S_MU_NODE_ROLE table consists of various fields, each holding specific information or linking keys about Node Roles data available in SAP. These include SYS_GROUP (Model), BO_NAME (Object Type), NODE_NAME (Node Name), ROLE_TYPE (Role Type)... 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. .
