FPLAA_CPY 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 "Information for Copying Partial Invoicing Plans" 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_FPLAA_CPY TYPE FPLAA_CPY.
The FPLAA_CPY table consists of various fields, each holding specific information or linking keys about Information for Copying Partial Invoicing Plans data available in SAP. These include FPART_TARGET (Billing/Invoicing Plan Type), FPTTP_TARGET (Date category), BEDAT_TARGET (Start date for billing plan/invoice plan), BEDAR_TARGET (Rule for Origin of Start Date of Billing/Invoicing Plan)... 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. .
