E2COSS2 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 Costs - Internal Postings - 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_E2COSS2 TYPE E2COSS2.
The E2COSS2 table consists of various fields, each holding specific information or linking keys about Total Costs - Internal Postings - One Period data available in SAP. These include WTGBTR (Field length 18), WOGBTR (Field length 18), WKGBTR (Field length 18), WKFBTR (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. .
