COEPL_P 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 "CO Object: LI Activity Types for Periodic Transfer Structure" 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_COEPL_P TYPE COEPL_P.
The COEPL_P table consists of various fields, each holding specific information or linking keys about CO Object: LI Activity Types for Periodic Transfer Structure data available in SAP. These include PERIO (Period), MEINH (Activity unit), LSTBTR (Activity Quantity), MEINB (Posted Activity Unit)... 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. .
