KPP0B 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 "CO planning processor: Screen fields initial screen" 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_KPP0B TYPE KPP0B.
The KPP0B table consists of various fields, each holding specific information or linking keys about CO planning processor: Screen fields initial screen data available in SAP. These include VALUE (Value in Characteristics Table), TEXT (Text, 40 Characters Long), INIT (Flag: Initial value chosen as select option)... 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. .
