RC2PH 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 "Master Recipe: Operation Overview Phases" 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_RC2PH TYPE RC2PH.
The RC2PH table consists of various fields, each holding specific information or linking keys about Master Recipe: Operation Overview Phases data available in SAP. These include INDEX_PLPO (Index referring to record table for items), PHSEQ (Control Recipe Destination), PLNKN (Number of the task list 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. .
