RMIPM2 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 "Objects in the MaintPlan" 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_RMIPM2 TYPE RMIPM2.
The RMIPM2 table consists of various fields, each holding specific information or linking keys about Objects in the MaintPlan data available in SAP. These include PLTXT (Description of functional location), EQUNR (Equipment Number), EQKTX (Description of technical object), BAUTL (Assembly)... 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. .
