COCM_MESS_CONTEXT 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 "Message Context for OCM Logs" 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_COCM_MESS_CONTEXT TYPE COCM_MESS_CONTEXT.
The COCM_MESS_CONTEXT table consists of various fields, each holding specific information or linking keys about Message Context for OCM Logs data available in SAP. These include FUNCT (Function to be carried out by system), CPUDT (Day On Which Accounting Document Was Entered), CPUTM (Time of Entry)... 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. .
