B60CH 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 "Direct input for characteristic values in demand management" 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_B60CH TYPE B60CH.
The B60CH table consists of various fields, each holding specific information or linking keys about Direct input for characteristic values in demand management data available in SAP. These include PDATU (Delivery/order finish date), CLINT (Internal Class Number), LNPOS (Row Number of Variant Table - External), EWAHR (Floating point field: quantity in characteristics planning)... 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. .
