CRAPO 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 "Transfer Structure for Capacities ==> APO Resources" 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_CRAPO TYPE CRAPO.
The CRAPO table consists of various fields, each holding specific information or linking keys about Transfer Structure for Capacities ==> APO Resources data available in SAP. These include R3ARBID (Object ID of the resource), R3KAPID (Capacity ID), UNIT (Base Unit of Measurement for Capacity), NAME (Resource Name)... 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. .
