FPLTS 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 "Dates in the Billing Plan already Billed." 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_FPLTS TYPE FPLTS.
The FPLTS table consists of various fields, each holding specific information or linking keys about Dates in the Billing Plan already Billed. data available in SAP. These include FPLTR (Item for billing plan/invoice plan/payment cards), WAERS (Currency Key), RFWRT (Reference value), PLMIN (Quantity is calculated positively, negatively or not at all)... 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. .
