ATPPLANT 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 "ATP Server: Plant Data for Availability Check" 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_ATPPLANT TYPE ATPPLANT.
The ATPPLANT table consists of various fields, each holding specific information or linking keys about ATP Server: Plant Data for Availability Check data available in SAP.
