COEJL_ONLY 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 "Non-key fields, only in COEJL (INCLUDE 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_COEJL_ONLY TYPE COEJL_ONLY.
The COEJL_ONLY table consists of various fields, each holding specific information or linking keys about Non-key fields, only in COEJL (INCLUDE structure) data available in SAP. These include LST001 (Activity Quantity), LST002 (Activity Quantity), LST003 (Activity Quantity), LST004 (Activity Quantity)... 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. .
