ERROR_TAB_RESCHED 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 "Output Structure / Rescheduling Messages" 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_ERROR_TAB_RESCHED TYPE ERROR_TAB_RESCHED.
The ERROR_TAB_RESCHED table consists of various fields, each holding specific information or linking keys about Output Structure / Rescheduling Messages data available in SAP. These include MSGID (Message identification), MSGTY (Message Type), MSGNO (System Message Number), MSGV1 (Message variable 01)... 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. .
