E2COSL2 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 "Total Activity Types - One Period" 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_E2COSL2 TYPE E2COSL2.
The E2COSL2 table consists of various fields, each holding specific information or linking keys about Total Activity Types - One Period data available in SAP. These include LSTBTR (Field length 18), KAPBTR (Field length 18), AUSBTR (Field length 18), DISBTR (Field length 18)... 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. .
