E2COST3 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 Prices - 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_E2COST3 TYPE E2COST3.
The E2COST3 table consists of various fields, each holding specific information or linking keys about Total Activity Prices - One Period data available in SAP. These include TKGBTR (Character field 13 digits), TKFBTR (Character field 13 digits), TKEBTR (Price Unit in Controlling Area Currency), TOGBTR (Character field 13 digits)... 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. .
